- Description
This ionogram was digitized from the original ISIS 1 analog telemetry data on 7-track tape using the facilities of the Data Evaluation Laboratory at GSFC (Code 500). This data restoration project is headed by Dr. R.F. Benson (GSFC, Code 673). Ionograms were digitized at the rate of 40,000 16-bit samples/sec. This sample rate is higher than the Nyquist frequency of 30 kHz. The sample frequency of 40 kHz provides a measurement every 25 microseconds corresponding to an apparent range (c*t/2) interval of 3.747 km. Each ionogram consists of a fixed-frequency and and a swept-frequency portion. The time resolution is typically 24 seconds.

- Description
This data set, provided by the Communications Research Centre (CRC) in Ottawa, Canada, consists of electron density profiles for the ionosphere above the F2 maximum (topside ionosphere). The data were computed from the orginal ionograms using Jackson's method (Jackson, Proceedings of the IEEE., p. 960, June 1969). ISIS-1 was launched on 1969-01-30 into an elliptical orbit (500-3500km) with an inclination of 88.4 degrees and ISIS-2 was launched on 1971-04-01 into an circular orbit at 1400 km with an inclination of 88.1 degrees. Both satellites were fully instrumented ionospheric observatories including sweep- and fixed-frequequency ionosondes, a VLF receiver, energetic and soft particle detectors, an ion mass spectrometer, an electrostatic analyzer, an Langmuir probe, a beacon transmitter, a cosmic noise experiment and ISIS 2 also carried two photometers. A tape recorder with 1-h capacity was included on both satellites. Data were also collected during overflights of several telemetry stations. The telemetry stations were in areas that provided primary data coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore, Australia, the UK, Norway, India, Japan, Antarctica, New Zealand, and Central Africa.

- Description
A 7-track ISIS 2 analog telemetry tape from Ottawa (#561) has been digitized using the GSFC facilities of the Data Evaluation Laboratory (DEL) within the Mission Operations and Data Systems Directorate (Code 500) at Goddard. The digitization was performed using an A/D converter board and software device driver compatible with the OS/2 operating system used by the 486-based Programmable Telemetry Processor (PTP) associated software has been installed on their PTP and de-bugged so that we now have a working system for making digital ISIS ionograms directly from the telemetry tapes. Earlier, we successfully digitized the PCM and NASA 36 bit time-code data from this same tape. The ionograms were digitized at the rate of 40,000 16-bit samples/sec. This sample rate is higher than the Nyquist frequency of 30 kHz appropriate for the post-detection ISIS 2 sounder-receiver video output which extends from DC to 15 kHz (see p. 50 of the 1971 ISIS 2 report by Daniels). The sample frequency of 40 kHz provides a measurement every 25 microseconds corresponding to an apparent range (ct/2) interval of 3.747 km. With the ISIS 2 prf of 45 sounder pulses/s, there are (1/45)/(2.5**(-5)) = 888.89 samples between each of the approximately 1015 sounder pulses per ionogram (including the fixed-frequency portion) or nearly 10**6 16-bit samples/ionogram (approximately 1.8 MBytes) for just the sounder-receiver video data. Adding header information, and the pcm data containing data from the other instruments, yields about 2 MBytes of data for the 22.5 s period corresponding to one ionogram. Two steps were taken in order to reduce this large volume of nearly 2 MBytes/ionogram. First, every four 25 microsecond samples following the sounder pulse were averaged. Second, the 16 bit samples were reduced to 8 bit samples. The first step decreased the apparent-range resolution to 15 km, but yielded high-quality ionograms because of the improved S/N due to the averaging.

- Description
A 7-track ISIS 2 analog telemetry tape from Ottawa (#561) has been digitized using the GSFC facilities of the Data Evaluation Laboratory (DEL) within the Mission Operations and Data Systems Directorate (Code 500) at Goddard. The digitization was performed using an A/D converter board and software device driver compatible with the OS/2 operating system used by the 486-based Programmable Telemetry Processor (PTP) associated software has been installed on their PTP and de-bugged so that we now have a working system for making digital ISIS ionograms directly from the telemetry tapes. Earlier, we successfully digitized the PCM and NASA 36 bit time-code data from this same tape. The ionograms were digitized at the rate of 40,000 16-bit samples/sec. This sample rate is higher than the Nyquist frequency of 30 kHz appropriate for the post-detection ISIS 2 sounder-receiver video output which extends from DC to 15 kHz (see p. 50 of the 1971 ISIS 2 report by Daniels). The sample frequency of 40 kHz provides a measurement every 25 microseconds corresponding to an apparent range (ct/2) interval of 3.747 km. With the ISIS 2 prf of 45 sounder pulses/s, there are (1/45)/(2.5**(-5)) = 888.89 samples between each of the approximately 1015 sounder pulses per ionogram (including the fixed-frequency portion) or nearly 10**6 16-bit samples/ionogram (approximately 1.8 MBytes) for just the sounder-receiver video data. Adding header information, and the pcm data containing data from the other instruments, yields about 2 MBytes of data for the 22.5 s period corresponding to one ionogram. Two steps were taken in order to reduce this large volume of nearly 2 MBytes/ionogram. First, every four 25 microsecond samples following the sounder pulse were averaged. Second, the 16 bit samples were reduced to 8 bit samples. The first step decreased the apparent-range resolution to 15 km, but yielded high-quality ionograms because of the improved S/N due to the averaging.

- I2_NEPROF_TOPIST (spase://NASA/NumericalData/ISIS2/SFS/TOPIST)
- Description
ISIS 2 was an ionospheric observatory instrumented with a sweep- and a fixed-frequency ionosonde, a VLF receiver, energetic and soft particle detectors, an ion mass spectrometer, an electrostatic probe, a retarding potential analyzer, a beacon transmitter, a cosmic noise experiment, and two photometers. Two long crossed-dipole antennas (73 and 18.7 m) were used for the sounding, VLF, and cosmic noise experiments. The spacecraft was spin-stabilized to about 2 rpm after antenna deployment. There were two basic orientation modes for the spacecraft, cartwheel and orbit-aligned. The spacecraft operated approximately the same length of time in each mode, remaining in one mode typically 3 to 5 months. The cartwheel mode with the axis perpendicular to the orbit plane was made available to provide ram and wake data for some experiments for each spin period, rather than for each orbit period. Attitude and spin information was obtained from a three-axis magnetometer and a sun sensor. Control of attitude and spin was possible by means of magnetic torquing. The experiment package also included a programmable tape recorder with a one hour capacity. For non-recorded observations, data from satellite and subsatellite regions were telemetered when the spacecraft was in the line of sight of a telemetry station. Telemetry stations were located so that primary data coverage was near the 80-deg-W meridian and near Hawaii, Singapore, Australia, England, France, Norway, India, Japan, Antarctica, New Zealand, and Central Africa. NASA support of the ISIS project was terminated on October 1, 1979. A significant amount of experimental data, however, was acquired after this date by the Canadian project team. ISIS 2 operations were terminated in Canada on March 9, 1984. The Radio Research Laboratories (Tokyo, Japan) then requested and received permission to reactivate ISIS 2. Regular ISIS 2 operations were started from Kashima, Japan, in early August 1984. ISIS 2 was deactivated effective 24, 1990. A data restoration effort began in the late 1990s and successfully saved a considerable portion of the high-resolution data before the telemetry tapes were discarted. The data set was generated from the averaged ionogram binary data (SPIO-00318) recorded by the Topside Sounder. The data are obtained with the TOPIST program, which analyzes the data, automatically scales the ionogram traces and resonances, and inverts the traces into an electron density profile. The same program is available for use to hand-scale the data if desired. Output data items include spacecraft position, electron density profile, assessment of quality, resonance and cut-off frequencies, and both the O-trace and X-trace.

- I2_NEPROF_TOPS (spase://NASA/NumericalData/ISIS2/SFS/TOPS)
- Description
This data set, provided by the Communications Research Centre (CRC) in Ottawa, Canada, consists of electron density profiles for the ionosphere above the F2 maximum (topside ionosphere). The data were computed from the orginal ionograms using Jackson's method (Jackson, Proceedings of the IEEE., p. 960, June 1969). ISIS-1 was launched on 1969-01-30 into an elliptical orbit (500-3500km) with an inclination of 88.4 degrees and ISIS-2 was launched on 1971-04-01 into an circular orbit at 1400 km with an inclination of 88.1 degrees. Both satellites were fully instrumented ionospheric observatories including sweep- and fixed-frequequency ionosondes, a VLF receiver, energetic and soft particle detectors, an ion mass spectrometer, an electrostatic analyzer, an Langmuir probe, a beacon transmitter, a cosmic noise experiment and ISIS 2 also carried two photometers. A tape recorder with 1-h capacity was included on both satellites. Data were also collected during overflights of several telemetry stations. The telemetry stations were in areas that provided primary data coverage near the 80-deg-W meridian and in areas near Hawaii, Singapore, Australia, the UK, Norway, India, Japan, Antarctica, New Zealand, and Central Africa.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 17 releases of IBEX-HI and/or IBEX-LO data covering 2009-2020. 2: This data set is from the Release 2 (6 months-cadence) IBEX-Hi map data for the year 2009 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 2 map numbers (1-2) with mission year 1 Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 8: This particular data set, denoted in the original ascii files as mapN for N=1-2, which indicates a map number, includes pixel map data from all directions (omnidirectional), CG, no SP, 6 month cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 17 releases of IBEX-HI and/or IBEX-LO data covering 2009-2020. 2: This data set is from the Release 2 (6 months-cadence) IBEX-Hi map data for the year 2009 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 2 map numbers (1-2) with mission year 1 Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 8: This particular data set, denoted in the original ascii files as mapN for N=1-2, which indicates a map number, includes pixel map data from all directions (omnidirectional), no CG, no SP, 6 month cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_yearN_cg for N 1 - 3, includes pixel map data from antiram direction (antiram-directional), CG, no SP, 1 year cadence.
- Modification History
Currently, the Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (6 months-cadence) IBEX-Hi map data for the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
Currently, the Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (6 months-cadence) IBEX-Hi map data for the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The newest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the years 2009-2012 in the form of Survival Probabilities tables. Each data directory related to survival probability has information about a different aspect of the transport through the heliosphere: a) deflection - angular deflection experienced between the termination shock and the observer. b) eloss - energy loss (or gain) between the termination shock and the observer. c) survpro - survival probability that an ENA passing through the termination shock will make it to 1AU. 3. For this release, the survival probabilities are only applied to the IBEX-HI data stream. Note that the energy loss is negligible, and the deflection angles in the inertial system are always smaller than 0.6 degrees or so. 4. Each directory has contains correction factors for data in the spacecraft frame (scf) and the inertial frame (1AU). The inertial frame (1AU) survival probabilities are used for the CG corrected data. The spacecraft frame factors are used for uncorrected data. The spacecraft frame files have the energy/direction shifts caused by the Earth/Spacecraft motion. This has a small effect on the survival probabilities (simply due to the energy shifts), but the deflection angles and energy shifts caused by this motion can be significant. 5. The deflection and energy shift files are not applied by the IBEX pipeline software. In theory, these could be applied to the CG corrected data after the fact. However, it is important to note that the spacecraft frame correction factors for energy and angle contain elements of the CG correction and 6. can yield confusing results when applied to the pipeline results. The data layout per frame consists of the following. For the spacecraft frame, there is a column for each ESA step, and a row for each angle bin (1 degree bins). Each number gives the probability at that angle and ESA for survival. The probability per angle is interpolated to the center of any particular angular bin being evaluated. In the inertial frame, the columns are the energies rather than ESA steps. 7. These are applied to the IBEX images that are given on the variable energy grid. For each image pixel, we take the energy and angle and use a 2D interpolation to get the survival probability. 8. The data consist of Survival Probabilities tables. Details of the data and enabled science from Release 10 are given in the following journal publication: 9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 10: http://doi.org/10.3847/1538-4365/aa66d8 8: This particular data set, denoted in the original ascii files as Data_Release_4\hs_transport\surv\o0NNNx.defl1au , where NNN=006-150 is an orbit number, and x = a or b for the orbit 130 or higher, indicates the first or the second half of the orbit, Survival Probabilities tables

The spacecraft frame factors are used for uncorrected data. The spacecraft frame files have the energy/direction shifts caused by the Earth/Spacecraft motion. This has a small effect on the survival probabilities (simply due to the energy shifts), but the deflection angles and energy shifts caused by this motion can be significant. 5. The deflection and energy shift files are not applied by the IBEX pipeline software. In theory, these could be applied to the CG corrected data after the fact. However, it is important to note that the spacecraft frame correction factors for energy and angle contain elements of the CG correction and 6. can yield confusing results when applied to the pipeline results. The data layout per frame consists of the following. For the spacecraft frame, there is a column for each ESA step, and a row for each angle bin (1 degree bins). Each number gives the probability at that angle and ESA for survival. The probability per angle is interpolated to the center of any particular angular bin being evaluated. In the inertial frame, the columns are the energies rather than ESA steps. 7. These are applied to the IBEX images that are given on the variable energy grid. For each image pixel, we take the energy and angle and use a 2D interpolation to get the survival probability. 8. The data consist of Survival Probabilities tables.

The latest Release 16 data extends through Map 22 and contains modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the years 2009-2012 in the form of Survival Probabilities tables. Each data directory related to survival probability has information about a different aspect of the transport through the heliosphere: a) deflection - angular deflection experienced between the termination shock and the observer. b) eloss - energy loss (or gain) between the termination shock and the observer. c) survpro - survival probability that an ENA passing through the termination shock will make it to 1AU. 3. For this release, the survival probabilities are only applied to the IBEX-HI data stream.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_yearN for N = 1 - 3, includes pixel map data from antiram direction (antiram-directional), no CG, no SP, 1 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2011. 2: This data set is from the Release 4 three-year IBEX-Hi map data for 2009-2011, in the form of omni-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 4 map numbers (1-6) with mission year (1-3) each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 8: This particular data set, denoted in the original ascii files as comb-year123, includes pixel map data from omni direction, noCG, noSP, 3 year cadence.
- Modification History
The Release 4 data extend through Map 6 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2011. 2: This data set is from the Release 4 three-year IBEX-Hi map data for 2009-2011, in the form of omni-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.) 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 4 map numbers (1-6) with mission year (1-3) each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 8: This particular data set, denoted in the original ascii files as comb-map1to6, includes pixel map data from omni direction, noCG, noSP, 6 maps or 3 year cadence.
- Modification History
The Release 4 data extend through Map 6 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of ram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_noSP_ram_N for N = 1 - 3, includes pixel map data from ram direction (ram-directional), no CG, no SP, 1 year cadence.
- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2012 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and withcorrection for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_tabular_antiram_yearN for N = 1 - 3, includes pixel map data from antiram direction (antiram-directional), no CG, SP, 1 year cadence.
- Modification History
The Release 4 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 6 (6 months-cadence) IBEX-Hi map data for the years 2009-2012 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and withcorrection for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4, 7.5 day-cadence IBEX-Hi data for the years 2009-2012 in the form of Survival Probabilities tables. Each data directory related to survival probability has information about a different aspect of the transport through the heliosphere: a) deflection - angular deflection experienced between the termination shock and the observer. b) eloss - energy loss (or gain) between the termination shock and the observer. c) survpro - survival probability that an ENA passing through the termination shock will make it to 1AU. 3. For this release, the survival probabilities are only applied to the IBEX-HI data stream. Note that the energy loss is negligible, and the deflection angles in the inertial system are always smaller than 0.6 degrees or so. 4. Each directory has contains correction factors for data in the spacecraft frame (scf) and the inertial frame (1AU). The inertial frame (1AU) survival probabilities are used for the CG corrected data. The spacecraft frame factors are used for uncorrected data. The spacecraft frame files have the energy/direction shifts caused by the Earth/Spacecraft motion. This has a small effect on the survival probabilities (simply due to the energy shifts), but the deflection angles and energy shifts caused by this motion can be significant. 5. The deflection and energy shift files are not applied by the IBEX pipeline software. In theory, these could be applied to the CG corrected data after the fact. However, it is important to note that the spacecraft frame correction factors for energy and angle contain elements of the CG correction and 6. can yield confusing results when applied to the pipeline results. The data layout per frame consists of the following. For the spacecraft frame, there is a column for each ESA step, and a row for each angle bin (1 degree bins). Each number gives the probability at that angle and ESA for survival. The probability per angle is interpolated to the center of any particular angular bin being evaluated. In the inertial frame, the columns are the energies rather than ESA steps. 7. These are applied to the IBEX images that are given on the variable energy grid. For each image pixel, we take the energy and angle and use a 2D interpolation to get the survival probability. 8. The data consist of Survival Probabilities tables. Details of the data and enabled science from Release 10 are given in the following journal publication: 9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 10: http://doi.org/10.3847/1538-4365/aa66d8 8: This particular data set, denoted in the original ascii files as Data_Release_4\hs_transport\surv\o0NNNx.survscf , where NNN=006-150 is an orbit number, and x = a or b for the orbit 130 or higher, indicates the first or the second half of the orbit, Survival Probabilities tables

The spacecraft frame factors are used for uncorrected data. The spacecraft frame files have the energy/direction shifts caused by the Earth/Spacecraft motion. This has a small effect on the survival probabilities (simply due to the energy shifts), but the deflection angles and energy shifts caused by this motion can be significant. 5. The deflection and energy shift files are not applied by the IBEX pipeline software. In theory, these could be applied to the CG corrected data after the fact. However, it is important to note that the spacecraft frame correction factors for energy and angle contain elements of the CG correction and 6. can yield confusing results when applied to the pipeline results. The data layout per frame consists of the following. For the spacecraft frame, there is a column for each ESA step, and a row for each angle bin (1 degree bins). Each number gives the probability at that angle and ESA for survival. The probability per angle is interpolated to the center of any particular angular bin being evaluated. In the inertial frame, the columns are the energies rather than ESA steps. 7. These are applied to the IBEX images that are given on the variable energy grid. For each image pixel, we take the energy and angle and use a 2D interpolation to get the survival probability. 8. The data consist of Survival Probabilities tables. Details of the data and enabled science from Release 10 are given in the following journal publication: 9: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 10: http://doi.org/10.3847/1538-4365/aa66d8 8: This particular data set, denoted in the original ascii files as Data_Release_4\hs_transport\surv\o0NNNx.survscf , where NNN=006-150 is an orbit number, and x = a or b for the orbit 130 or higher, indicates the first or the second half of the orbit, Survival Probabilities tables
- Modification History
The latest Release 16 data extends through Map 22 and contains modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Var Energy Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the years 2009-2013 in the form of antiram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SCF Frame 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (6 months-cadence) IBEX-Hi map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_tabular_ram_cg_yearN for N=1,5, includes pixel map data from ram direction (ram-directional), CG, SP, 1 year cadence.
- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Mono Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Var Energy Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the years 2009-2013 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al.

- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_mapX, where X = 1-10 are pixel map data from all directions (omnidirectional), no CG, no SP, 6 month cadence.
- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with noCompton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1 year-cadence) IBEX-Hi map data for the years 2009-2013 in the form of ram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_noSP_ram_yearN for N=1,5, includes pixel map data from ram direction (ram-directional), no CG, no SP, 1 year cadence.
- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Var Energy Inertial Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_tabular_mapX, where X = 1-10 are pixel map data from all directions (omnidirectional), no CG, SP, 6 month cadence.

The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Hi map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with noCompton-Getting correction (nocg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-5-year-average) IBEX-Hi map data for the years 2009-2014 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 8 IBEX-Hi map data for the years 2009-2014 (5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 8 IBEX-Hi map data for the years 2009-2014 (5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 8 IBEX-Hi map data for the years 2009-2014 (5 year-cadence) in the form of omnidirectional GDF (Globally Distributed Flux) ENA (hydrogen) fluxes between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. gdf = Globally Distributed Flux. 7.

The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_cg_yearN for N=1,7, includes pixel map data from antiram direction, CG, noSP, 1 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of antiram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_cg_ single, includes pixel map data from antiram direction, CG, noSP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for the first seven years, 2009-2015, with multiple versions of data sets including no corrections, full corrections for spacecraft motion, and corrections for ENA survival probability between 1 and 100 AU. 3: The data consist of all-sky maps in Solar West Ecliptic angles of ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. 7: nocg = no Compton-Getting corrections 8: sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. 9: noSP - no survival probability corrections have been applied to the data. 10: omni = data from all directions. 11: ram = data was collected when the spacecraft was ramming into the incoming ENAs. 12: antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 13: The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015). 14: Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 15: Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 16: Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 17: Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 18: Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 19: Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 20: Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 21: Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 22: Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 23: Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 24: Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 25: Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 26: Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 27: Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 28: This particular data set, denoted in the original ascii files as hvset_cg_mapN for N=1,14, includes pixel map data from all directions (omnidirectional), CG, no SP, 6 month cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of omni-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_cg_ single, includes pixel map data from omni direction, CG, noSP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 one-year IBEX-Hi map data for the first seven years, 2009-2015, in the form of ram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_noSP_ram_cg_yearN for N=1,7, includes pixel map data from RAM direction (ram-direction), CG, noSP, 1 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of ram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (1-year-cadence) IBEX-Hi map data for the first seven years, 2009-2015, in the form of anti-RAM-directional fluxes with corrections for spacecraft motion (cg: Compton-Getting) and with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_antiram_cg_yearN for N=1,7, includes pixel map data from antiRAM direction (antiRAMdirectional), CG, SP, 1 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of antiram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) and with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_antiram_cg_single, includes pixel map data from antiram direction, CG,SP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes with corrections (cg) for spacecraft motion (Compton-Getting) and corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_cg_tabular_mapN for N=1,14, includes pixel map data from all directions (omnidirectional), CG, SP, 6 month cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of omni-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) and with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_cg_tabular_ single, includes pixel map data from omni direction, CG,SP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_ram_cg_yearN for N=1,7, includes pixel map data from RAM direction (RAMdirectional), CG, SP, 1 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of ram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) and with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_ram_cg_single, includes pixel map data from ram direction, CG,SP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 one-year IBEX-Hi map data for the first seven years, 2009-2015, in the form of antiram-direction fluxes with no corrections for spacecraft motion (nocg: no Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_yearN for N=1,7, includes pixel map data from antiram direction, CG, noSP, 1 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of antiram-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_single, includes pixel map data from antiram direction, noCG, noSP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes without any corrections (nocg) for spacecraft motion (Compton-Getting) and ENA survival probability (nosp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_mapN for N=1,14, includes pixel map data from all directions (omnidirectional), no CG, no SP, 6 month cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of omni-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_single, includes pixel map data from omni direction, noCG, noSP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 one-year IBEX-Hi map data for the first seven years, 2009-2015, in the form of ram-direction fluxes with no corrections for spacecraft motion (nocg: no Compton-Getting) and with no corrections (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 one-year IBEX-Hi map data for the first seven years, 2009-2015, in the form of antiram-direction fluxes with no corrections for spacecraft motion (nocg: no Compton-Getting) and with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_noSP_antiram_yearN for N=1,7, includes pixelmap data from anti ramdirection, noCG, SP, 1 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of antiram-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) but with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_antiram_single, includes pixel map data from antiram direction, noCG, SP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (6 months-cadence) IBEX-Hi map data for the first seven years, 2009-2015, with multiple versions of data sets including no corrections, full corrections for spacecraft motion, and corrections for ENA survival probability between 1 and 100 AU. 3: The data consist of all-sky maps in Solar West Ecliptic angles of ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. 7: nocg = no Compton-Getting corrections 8: sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. 9: noSP - no survival probability corrections have been applied to the data. 10: omni = data from all directions. 11: ram = data was collected when the spacecraft was ramming into the incoming ENAs. 12: antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 13: The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015). 14: Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 15: Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 16: Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 17: Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 18: Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 19: Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 20: Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 21: Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 22: Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 23: Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 24: Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 25: Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 26: Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 27: Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 28: This particular data set, denoted in the original ascii files as hvset_tabular_mapN for N=1,14, includes pixel map data from all directions (omnidirectional), no CG, SP, 6 month cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 seven-year IBEX-Hi map data for 2009-2015, in the form of omni-direction fluxes with no corrections for spacecraft motion (nocg: Compton-Getting) but with corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: This particular data set, denoted in the original ascii files as hvset_tabular_single, includes pixel map data from omni direction, noCG, noSP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: This data set is from the IBEX-Hi Release 12 Count Data for Magnetospheric Imaging. This release provides data for various IBEX orbits from 23 (2009-03-26) to 207b (2013-05-30). The data include 21 orbits from IBEX-Hi 6-degree histogram ENA count data, which is primarily what have been used in IBEX magnetospheric studies. 3. The data consist of IBEX-Hi Count Data for Magnetospheric Imaging during instrument pointing in spin angle 0 - 360 degrees between the north and south Ecliptic poles. Spin angle zero corresponds to the north Ecliptic pole. Counts come from IBEX-Hi energy bands 2-6 in numerical data form corresponding to energy bins 2-6: 2) ~0.71, 3) ~1.11, 4) ~1.74, 5) ~2.73, 6) ~4.3 keV. Background counts have not been removed. Counts are separated into 6-degree latitudinal bins, with each # angle label representing the center of the bin. Details of the data and enabled science from Release 12 are given in the following journal publications: McComas et al. 2011,2012b; Fuselier et al. 2010, 2015; Petrinec et al. 2011; Ogasawara et al. 2013, 2019; and Dayeh et al. 2015Data Location: http://ibex.swri.edu/ibexpublicdata/Data_Release_12/index.htmlContact: Maher Dayeh, Southwest Research Institute, San Antonio, TX maldayeh@swri.edu Orbit Start and End Times: 23: 2009-03-26 21:09:00.318 to 2009-04-03 16:07:51.743 24: 2009-04-03 12:10:21.253 to 2009-04-11 08:15:09.669 25: 2009-04-11 05:06:40.967 to 2009-04-18 22:05:11.125 27: 2009-04-26 08:27:40.916 to 2009-05-04 05:31:06.519 28: 2009-05-04 02:02:57.673 to 2009-05-11 21:13:47.596 29: 2009-05-11 17:27:02.484 to 2009-05-19 19:27:18.831 51: 2009-10-26 08:19:34.905 to 2009-11-03 02:38:01.730 52: 2009-11-02 22:34:07.792 to 2009-11-10 19:03:55.230 53: 2009-11-10 15:46:22.161 to 2009-11-18 10:58:17.674 55: 2009-11-25 23:44:19.069 to 2009-12-03 11:26:37.151 56: 2009-12-03 08:22:31.792 to 2009-12-10 22:03:52.604 57: 2009-12-10 18:55:33.969 to 2009-12-18 06:58:47.247 72: 2010-04-04 11:17:28.386 to 2010-04-12 09:13:51.008 74: 2010-04-19 14:09:01.851 to 2010-04-27 03:44:14.913 77: 2010-05-12 01:33:51.796 to 2010-05-19 20:43:01.583 78: 2010-05-19 17:33:48.047 to 2010-05-27 13:02:03.396 103: 2010-11-26 07:56:05.324 to 2010-12-04 04:11:44.879 187a: 2012-11-21 00:17:13.430 to 2012-11-25 00:40:26.707 188b: 2012-12-03 12:46:18.859 to 2012-12-08 00:44:50.846 206a: 2013-05-13 23:15:27.433 to 2013-05-17 12:19:58.215 207b: 2013-05-26 12:21:08.868 to 2013-05-30 23:14:44.989 For the first two and a half years of science operations (through Orbit 127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once each orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130 onward are split into two segments, 'a' and 'b'. Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step (ESA1) in exchange for doubling the statistical sampling of ESA3 (center energy ~1.1 keV).

Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: This data set is from the Release 13 one-year IBEX-Hi map data for the nine years, 2009-2018, in the form of antiram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV.

The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 13 map numbers (1-20) with mission year (1-10), orbits (11-431bb), and dates (12/25/2008-12/26/2018); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: year 8, orbits 311a-330b, dates 12/24/2015-06/23/2016 Map 16: year 8, orbits 331a-351a, dates 06/24/2016-12/26/2016 Map 17: year 9, orbits 351b-371a, dates 12/26/2016-06/25/2017 Map 18: year 9, orbits 371b-391a, dates 06/25/2017-12/25/2017 Map 19: year 10, orbits 391a-411b, dates 12/25/2017-06/28/2018 Map 20: year 10, orbits 412a-431b, dates 06/29/2018-12/26/2018 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_cg_yearN for N=8, includes pixel map data from antiram direction, CG, noSP, 1 year cadence.
- Modification History
The Release 13 data extend through Map 20 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: This data set is from the Release 13 one-year IBEX-Hi map data for the nine years, 2009-2018, in the form of ram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 13 map numbers (1-20) with mission year (1-10), orbits (11-431bb), and dates (12/25/2008-12/26/2018); each year is associated with two consecutive maps; Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: year 8, orbits 311a-330b, dates 12/24/2015-06/23/2016 Map 16: year 8, orbits 331a-351a, dates 06/24/2016-12/26/2016 Map 17: year 9, orbits 351b-371a, dates 12/26/2016-06/25/2017 Map 18: year 9, orbits 371b-391a, dates 06/25/2017-12/25/2017 Map 19: year 10, orbits 391a-411b, dates 12/25/2017-06/28/2018 Map 20: year 10, orbits 412a-431b, dates 06/29/2018-12/26/2018 8: This particular data set, denoted in the original ascii files as hvset_noSP_ram_cg_yearN for N=8, includes pixel map data from antiram direction, CG, noSP, 1 year cadence.
- Modification History
The Release 13 data extend through Map 20 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: This data set is derived from the Release 14 three-year IBEX-Hi map data with two-year overlaps to adjacent maps, 2009-2011, 2010-2012, 2011-2013, and so forth through 2015-2017 from ram-direction fluxes with corrections for spacecraft motion (cg: Compton-Getting) but with no corrections (sp) for ENA survival probability between 1 and 100 AU. The data set parameters include line-of-sight (LOS) integrated pressures separately computed from the Global Distributed Flux (GDF), the ribbon flux, and the total of both LOS pressures. Additionally there are signal/noise ratios for the GDF, ribbon, and total pressures. Finally, there are power-law slope and values for the GDF differential flux, also including signal/noise of the slope. 3: The data consist of ram-direction sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for the above parameters. 4: Details of the data and enabled science from Release 14 are given in the following journal publication: Schwadron, N. A., et al. (2018), Time Dependence of the IBEX Ribbon and the Globally Distributed Energetic Neutral Atom Flux Using the First 9 Years of Observations https://iopscience.iop.org /article/10.3847/1538-4365/aae48e/meta 5: The following codes are used to define dataset types in the multiple IBEX data releases: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 6: This particular dataset denoted in the original ascii files as: -- GDFPressure: Globally Distributed Flux Line-of-Sight Integrated Pressure in pdyne-au/cm^2 -- GDFSlope: Power-Law Slope of the differential flux spectrum for the Globally Distributed Flux -- GDFSlopeSN: Signal/Noise ratio of the GDF differential flux power-law slope where noise represents uncertainty -- GDFSN: Globally Distributed Flux Signal/Noise, where Noise is defined as the uncertainty and the Signal is GDF Line-of-Sight -integrated pressure -- RibbonPressure: Ribbon Line-of-Sight Integrated Pressure in pdyne-au/cm^2 -- RibbonSN: Ribbon Signal/Noise, where Noise is defined as the uncertainty and the Signal is GDF Line-of-Sight -integrated pressure -- TotPressure: Total Pressure in ENA maps including both the GDF and Ribbon. Line-of-Sight Integrated Pressure in pdyne-au/cm^2 -- TotSN: Total Pressure Signal-to-Noise where noise represents uncertainty and signal represents the total LOS-integrated pressure
- Modification History
The Release 14 data extend through Map 20 and contain modifications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 15 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV.

The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. ribcen = maps are in a ribbon centered frame. 7.

- Modification History
The Release 15 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 15 (2 or 3 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al.

- Modification History
The Release 15 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11-year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_antiram_cg_single includes pixel map data from antiram direction (antiram-directional), CG, NOSP, 11 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_antiram_cg_N for N=2009,2019, includes pixel map data from antiram direction (antiram-directional), CG, NOSP, 1 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_cg_single\hv60.hide-trp-mono_80-M-V , where M = 0.71, 1.11, 1.74, 2.73, 4.29 showing the energy of the channel, and V = 'flux', 'fvar', or 'fsnr', includes pixel map data from antiram direction, CG, no SP, mono-energy, 11 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_cg_NX for N=2009,2019, which indicates a year data collected, and X = A or B, showing first or second half of the year, includes pixel map data from all directions (omnidirectional), CG, no SP, 6 month cadence.

This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data averaged for the years 2009-2019 in the form of ANTIRAMdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 16 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: This particular data set, denoted in the original ascii files as hvset_cg_tabular_single, includes pixel map data from all directions (omnidirectional), CG, SP, 11 year cadence.
- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 (3 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data averaged for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp)mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (11 year-cadence) IBEX-Hi map data averaged for the years 2009-2019 in the form of RAMdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of antiram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and withcorrection for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and with correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (6 months-cadence) IBEX-Hi map data for the years 2009-2019 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 (1 year-cadence) IBEX-Hi map data for the years 2009-2019 in the form of ram-directionl ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and withcorrection for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU in Equatorial Coordinates. 3. The data consist of all-sky maps in Solar Equatorial Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 16 IBEX-Hi map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU in Galactic Coordinates. 3. The data consist of all-sky maps in Solar Galactic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

The Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of omni-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of omni-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (14 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5. The following list associates Release 18 map numbers (1-28) with mission year (1-14), orbits (11-592B), and dates (12/25/2008-12/26/2022): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: year 11, orbits 452a-471b, dates 06/27/2019 . 12/26/2019 Map 23: year 12, orbits 472a-491b, dates 12/26/2019 . 06/24/2020 Map 24: year 12, orbits 492a-511b, dates 06/25/2020 . 12/24/2020 Map 25: year 13, orbits 512a-531b, dates 12/24/2020 . 06/24/2021 Map 26: year 13, orbits 532a-552b, dates 06/25/2021 . 12/27/2021 Map 27: year 14, orbits 552a-572b, dates 12/27/2021 . 06/26/2022 Map 28: year 14, orbits 572a-592b, dates 06/26/2022 . 12/26/2022 6: This particular data set, denoted in the original ascii files as hvset_cg_tabular_ram_2009-2022/hv60.hide-trp-flux100-hi-R-F.txt, where R shows the energy level from 2 to 6, and F shows the variable: 'cnts', 'flux', 'fexp', 'ener', 'fsnr', 'fvar', or 'numb' includes pixel map data from RAM direction (ramdirectional), CG, SP, 14 year cadence.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. gdf = globally distributed flux maps ribbon = ribbon maps 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) mono-energy (mono) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6. The following list associates Release 18 map numbers (1-28) with mission year (1-14), orbits (11-592B), and dates (12/25/2008-12/26/2022): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: year 11, orbits 452a-471b, dates 06/27/2019 . 12/26/2019 Map 23: year 12, orbits 472a-491b, dates 12/26/2019 . 06/24/2020 Map 24: year 12, orbits 492a-511b, dates 06/25/2020 . 12/24/2020 Map 25: year 13, orbits 512a-531b, dates 12/24/2020 . 06/24/2021 Map 26: year 13, orbits 532a-552b, dates 06/25/2021 . 12/27/2021 Map 27: year 14, orbits 552a-572b, dates 12/27/2021 . 06/26/2022 Map 28: year 14, orbits 572a-592b, dates 06/26/2022 . 12/26/2022 7: This particular data set, denoted in the original ascii files as hvset_noSP_antiram_N/hv60.hide-trp-flux100-hi-R-F.txt, where N is the year from 2009 to 2022, R shows the energy level from 2 to 6, and F shows the variable: 'cnts', 'flux', 'fexp', 'ener', 'fsnr', 'fvar', or 'numb' includes pixel map data from ANTIRAM direction (antiramdirectional), no CG, no SP, 6 month cadence.

There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of omni-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5.

This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of antiram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of omni-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (6 months-cadence) IBEX-Hi map data for the years 2009-2022 in the form of omnidirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and with correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU in equatorial coordinates. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 IBEX-Hi map data for the years 2009-2022 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU in galactic coordinates. 3. The data consist of all-sky maps in Solar Galactic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 4. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 5.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of ramdirectional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2022. 2: This data set is from the Release 3, 7.5 days cadence, IBEX-Lo data for the years 2009 - 2010 contains data used in the publication of Moebius et al., 2012, Interstellar Gas Flow Parameters Derived from IBEX-Lo Observations in 2009 and 2010 Analytical Analysis and Bzowski et al., 2012, Neutral interstellar helium parameters based on IBEX-Lo observations and test particle calculations. The data are the 6 degree resolution corrected histogram data and the observation time periods in one csv file for each orbit for both the angular fit analysis and the count rate analysis. 3: Additional publications: Bzowski et al., 2012, Neutral interstellar helium parameters based on IBEX-Lo observations and test particle calculations; and Hlond et al., 2012, Precision Pointing of IBEX-Lo Observations. 4: Data Selection: In order to determine accurately the interstellar gas flow vector, the pointing of IBEX-Lo has to be known to about 0.1 degree accuracy for the observations used in this analysis. It is demonstrated that the pointing of the IBEX-Lo star sensor and of the spacecraft star tracker agree within this prescribed accuracy for time periods of simultaneous good observations (Hlond et al., 2012). The data used from time periods when the IBEX star tracker, which provides precision pointing information for the routine data processing, was operating within its specifications for all analysis that requires exact pointing knowledge, such as the evaluation of the flow distributions in latitude. However, the determination of the ISM flow maximum in ecliptic longitude only requires the use of the count rates, obtained over plus-minus 3 sigma of the angular distribution from the latitude peak position, as a function of longitude, so this requirement can be relaxed. 5: During the analysis, it was found that the data transfer through the CEU that formats the information for the telemetry slows down because of the total traffic across the interface and the computational load event rates that exceed about 10 counts/s, as observed during the He ISM flow peak. This slow down produces a modulation in the high-resolution data according to the accumulation scheme into 6 deg sectors. Therefore, the only data integrated 6-deg sector for He used in this analysis. In addition, IBEX-Lo detects background electrons, which are identified as invalid events by the TOF spectrometer, but they have to be removed by the CEU, which adds to its load and the slow down when electron rates increase. 6: For this analysis, a list of valid time periods was compiled for the ISM flow analysis that is used throughout this paper and also in the analysis by Bzowski et al. (2012). Excluded from this list are time periods, for which the following conditions apply: 7: IBEX is close to the magnetosphere, where IBEX-Lo observes high count rates of magnetospheric ENAs and ions, based on angular ranges outside the ISM flow distribution. 8: The Moon is in the IBEX FoV. These times are taken from the ISOC command files, which contain special commanding for the star sensor. 9: The electron rates for IBEX-Lo are high. These times are identified in the IBEX-Lo TOF count rates, when the otherwise very stable base count rate outside the ISM flow direction is exceeded by more than a factor of 1.6 (safely above any stochastic fluctuations of the base count rate, but low enough to indicate any significant electron rate increases). 10: The star tracker function has been impaired. This affects the determination of the ISM peak location and width in latitude. 11: No further culling for increased background counts (routinely performed for suprathermal ENA observations (McComas et al. 2009b) is necessary for ISM flow observations because of the concentrated angular distributions at much higher rates. The angular distribution analysis, in general, is performed on much shorter .good. time periods than the count rate analysis because nominal operation of the star tracker is required. Because the rate analysis requires contiguous time sections of fixed length to achieve approximately comparable counting statistics for each data point, very small portions at the beginning or end of the .good. time intervals may be unused, which accounts for the occasional foreshortening of the .good. time intervals for the rate analysis at the beginning or the end. 12: McComas, D.

- Modification History
The latest Release 16 data extends through Map 22 and contains modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (3-year-average of 6-month-cadence maps) IBEX-Lo map data for the first s3 years, 2009-2012, in the form of fluxes with correction for spacecraft motion (cg) (Compton-Getting) and with applied ENA survival probability correction (sp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 4 (3-year-average of 6-month-cadence maps) IBEX-Lo map data for the first s3 years, 2009-2012, in the form of ramdirectional fluxes with correction for spacecraft motion (cg) (Compton-Getting) and with applied ENA survival probability correction (sp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files in the map_ram folder, includes pixel map data from ram direction (ramdirectional), CG, SP, 3 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- IBEX_H3_ENA_LO_R06_SCHWADRON-H (spase://VSPO/NumericalData/IBEX/H3/ENA/Lo/R06-H/P2hr)
- Description
This data set is from the IBEX-Lo Release 6 Primary Hydrogen Data Rate Files. The IBEX sixth data release contains data and related information connected with the publication of Schwadron et al., 2014, SOLAR RADIATION PRESSURE AND LOCAL INTERSTELLAR MEDIUM FLOW PARAMETERS FROM INTERSTELLAR BOUNDARY EXPLORER LOW ENERGY HYDROGEN MEASUREMENTS. Neutral hydrogen atoms that travel into the heliosphere from the local interstellar medium (LISM) experience strong effects due to charge exchange and radiation pressure from resonant absorption and re-emission of Lya. The radiation pressure roughly compensates for the solar gravity. As a result, interstellar hydrogen atoms move along trajectories that are quite different than those of heavier interstellar species such as helium and oxygen, which experience relatively weak radiation pressure. Charge exchange leads to the loss of primary neutrals from the LISM and the addition of new secondary neutrals from the heliosheath. IBEX observations show clear effects of radiation pressure in a large longitudinal shift in the peak of interstellar hydrogen compared with that of interstellar helium. Here, we compare results from the Lee et al. interstellar neutral model with IBEX-Lo hydrogen observations to describe the distribution of hydrogen near 1 AU and provide new estimates of the solar radiation pressure. We find over the period analyzed from 2009 to 2011 that radiation pressure divided by the gravitational force (.) has increased slightly from mu = 0.94 +- 0.04 in 2009 to mu = 1.01 +- 0.05 in 2011. We have also derived the speed, temperature, source longitude, and latitude of the neutral H atoms and find that these parameters are roughly consistent with those of interstellar He, particularly when considering the filtration effects that act on H in the outer heliosheath. Thus, our analysis shows that over the period from 2009 to 2011, we observe signatures of neutral H consistent with the primary distribution of atoms from the LISM and a radiation pressure that increases in the early rise of solar activity. Data rate files are listed by orbit number: o00XX-rate12.txt where XX corresponds to the orbit number. The data rate files contain five data columns correspond to: isector, rate (ESA1), uncertainty(ESA1), rate(ESA2), uncertainty (ESA2). All rates in counts/sec. The methods used to estimate these background-corrected count rates are discussed by Schwadron et al. (2013). Because of background correction some of the listed rates are negative, but these are typically negative values near 0 within statistical uncertainties. isector: 0 - 30 isector corresponds to the spin-sector of the IBEX-Hi sensor The spinning spacecraft moves the sensors from 0 to 360 in a great-circle where the spin-axis is directed with RA and DEC coordinates given in the inertial pointing file. Sector 0 corresponds to the spin sector whose center in spin angle points exactly to the North Ecliptic Pole (NEP). hi-spinphase (deg) = isector*6.0 lo-spinphase (deg) = hi-spinphase +/- 180.0 In the current compilation, the time periods have been sub-divided into 512-spin time periods and thus synchronized with the internal accumulation periods of the onboard Histograms reported here and with the prescribed 512-spin accumulation. Therefore, some of the periods have slightly different start times and truncated to match the last complete 512-spin period at the end. Orbit 13 was omitted from the current compilation because several data gaps due to still ongoing commanding during that orbit cut into the prescribed 512 spin cadence. Also, in Data Release 3, the start and end times were slightly different from Table 1 to match the cadence chosen for the data. As used in the 2012 ApJ Suppl publications, Golden Triple Hydrogen counts detected in IBEX-Lo energy step 2 in 6o resolution are reported, which reflect H sputtered off the IBEX-Lo conversion surface by incoming interstellar He, as described in Moebius et al. (2012). The data rate files are organized as follows: The first line in the header contains column labels for 6 data columns, as listed below The next header line includes the start time (in GPS), end time (in GPS), and accumulated time (in seconds). This line is repeated for each 512-spin time period. For the first two and a half years of science operations (through Orbit 127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once each orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130 onward are split into two segments, 'a' and 'b'. Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step (ESA1) in exchange for doubling the statistical sampling of ESA3 (center energy ~1.1 keV).

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: This data set is from the IBEX-Lo Release 6 He Data (Sputtered H) Counts.. Data files are listed by orbit number: IBEX_Lo_o00XX_Y_HB_and_DE_report.csv where XX corresponds to the orbit number and Y to the sequence number of separately listed time periods in the respective orbit. The format in the file is listed below. The data are given accumulated over 512 spins each (. 2 hours) in time blocks separated by dashed lines. Provided are the data for Good Times of Angular Distributions. given in Table 1 of Moebius et al. (2012, ApJ Suppl, 198, 11, doi:10.1088/0067-0049/198/2/11). The description of the data selection is found in the file Moebius_etal_2012-ApJ-Suppl_Data-Description.pdf. These data were released as aggregate data for the entire time periods listed along with the publication of the 2012 ApJ Suppl publications. See IBEX Data Release 3: http://ibex.swri.edu/researchers/publicdata.shtml#dr3 In the current compilation, the time periods have been sub-divided into 512-spin time periods and thus synchronized with the internal accumulation periods of the onboard Histograms reported here and with the prescribed 512-spin accumulation. Therefore, some of the periods have slightly different start times and truncated to match the last complete 512-spin period at the end. Orbit 13 was omitted from the current compilation because several data gaps due to still ongoing commanding during that orbit cut into the prescribed 512 spin cadence. Also, in Data Release 3, the start and end times were slightly different from Table 1 to match the cadence chosen for the data. As used in the 2012 ApJ Suppl publications, Golden Triple Hydrogen counts detected in IBEX-Lo energy step 2 in 6o resolution are reported, which reflect H sputtered off the IBEX-Lo conversion surface by incoming interstellar He, as described in Moebius et al. (2012). The data rate files are organized as follows: The first line in the header contains column labels for 6 data columns, as listed below The next header line includes the start time (in GPS), end time (in GPS), and accumulated time (in seconds). This line is repeated for each 512-spin time period. Column 1 : The center of each 6 degree angular bin in NEP as calculated using the phase in the HB file. 0 . 354 Degrees corresponds to the spin-angle counted from the North Ecliptic Pole (NEP). The spinning spacecraft moves both sensors from 0 to 360 in a great-circle where the spin-axis is directed with RA and DEC coordinates given in the inertial pointing file. Spin angle 0 corresponds to the spin sector whose center in spin angle points exactly to the North Ecliptic Pole(NEP). RA and DEC refer here to solar Ecliptic east longitude and latitude. Column 2 : Start time of the 512 spin bin in GPS Column 3 : Start time of the 512 spin bin in YYYY/MM:DD:HH:MM:SS format Column 4 : Counts in the Hydrogen histogram bins (HB-Counts) Column 5 : Same as column 1 except this was determined from the DE file, here as a check to make sure there were no missing bins in the HB file Column 6 : Counts listed as GOLDEN HYDROGEN in the direct events (DE_Counts) Note: The HB_Counts are used in the analysis to normalized DE_Counts for digital buffer and telemetry limitations during high count rate time periods, as they occur during the interstellar flow observations. Usually, HB_Counts = DE_Counts. However, during times when the count rates do not exceed the telemetry capability or not by much, occasionally DE_Counts > HB_Counts due to the finite digital angular binning by time increments of 4.1 ms, equivalent to . 0.075o in spin angle, which can lead to different binning in DE and HB at the boundaries of the 6o angular bins. Still, the HB_Count normalization should be used. The related angular uncertainty of the accumulated counts is =0.075o and thus smaller than the overall pointing accuracy as reported by Hlond et al. (2012, ApJ Suppl, 198, 9, doi:10.1088/0067-0049/198/2/9) For the first two and a half years of science operations (through Orbit 127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once each orbit (around perigee), leading to bands of sky viewing centered 7.5 apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a).

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 7 (6 months-cadence) IBEX-Lo map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes with no corrections (nocg) for spacecraft motion (Compton-Getting) and no ENA survival probability (nosp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Lo map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with noCompton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction (nosp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 3-8 in numerical data form. Energy channels 3-8 have FWHM ranges with the corresponding center-point energies respectively 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 7 (6 months-cadence) IBEX-Lo map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes with no corrections (nocg) for spacecraft motion (Compton-Getting) and with ENA survival probability (sp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_mapN for N=1,10, includes pixel map data from all directions (omnidirectional), no CG, SP, 6 month cadence.
- Modification History
The Release 7 data extend through Map 10 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 7 (1-to-10-map-average) IBEX-Lo map data for the years 2009-2014 in the form of omnidirectional ENA (hydrogen) fluxes with noCompton-Getting correction (nocg) of flux spectra for spacecraft motion and correction (sp) for ENA survival probability in Var Energy SC Frame between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 3-8 in numerical data form. Energy channels 3-8 have FWHM ranges with the corresponding center-point energies respectively 0.055, 0.110, 0.209, 0.439, 0.872, 1.821 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mif = Mono Inertial Frame veif = Var Energy Inertial Frame vescf = Var Energy SC Frame 7.

- Modification History
The Release 7 data extend through Maps 1-10. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 8 IBEX-Lo map data for the years 2009-2014 (5 year-cadence) in the form of omnidirectional ENA (hydrogen) fluxes between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The latest Release 16 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 8 IBEX-Lo map data for the years 2009-2014 (5 year-cadence) in the form of omnidirectional GDF (Globally Distributed Flux) ENA (hydrogen) fluxes between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. gdf = Globally Distributed Flux. 7.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 14 releases of IBEX-HI and/or IBEX-LO data covering 2009-2018. 2: IBEX-Lo Interstellar Neutral Histogram Counts and Direct Event Counts Data description: Interstellar neutral (ISN) histogram and direct event counts for each of the 60 IBEX-Lo angular bins. The data includes start and end times for each 512 spin period in GPS time as well as total accumulation times. Data files are in CSV format and are labelled according to their IBEX orbit and orbit arc. Data are collected for periods within the ISN goodtimes. The analyses of the IBEX He and H ISN flow distributions within this release are based on these data sets. 1. Golden triples 2. Hydrogen time-of-flight 3. Energy Steps 1-3 are included during non-special mode periods. ISN data product QA checks: All ISN season orbits are checked for contaminating backgrounds around the ISN peak itself. Times with high backgrounds are eliminated. Background threshold for this test is determined orbit by orbit using sample quiet times. Times when the TOF 2 rate exceeds this background by 60% are excluded. Times with spin issues are excluded Times with special operations are excluded (gain tests, etc.) Remaining times are included in ISN data products and the resulting ISN data products are checked for continuity (time and angle), and suppression (loss of direct events due to instrument throttling). 3: Reference: Schwadron et al. 2016, ApJ, 828:81, Determination of Interstellar O Parameters Using the First Two Years of Data from the Interstellar Boundary Explorer. 4: Data Location: https://ibex.princeton.edu/DataRelease 6: Orbit Start and End Times: 7: 23: 2009-03-26 21:09:00.318 to 2009-04-03 16:07:51.743 8: 24: 2009-04-03 12:10:21.253 to 2009-04-11 08:15:09.669 9: 25: 2009-04-11 05:06:40.967 to 2009-04-18 22:05:11.125 10: 27: 2009-04-26 08:27:40.916 to 2009-05-04 05:31:06.519 11: 28: 2009-05-04 02:02:57.673 to 2009-05-11 21:13:47.596 12: 29: 2009-05-11 17:27:02.484 to 2009-05-19 19:27:18.831 13: 51: 2009-10-26 08:19:34.905 to 2009-11-03 02:38:01.730 14: 52: 2009-11-02 22:34:07.792 to 2009-11-10 19:03:55.230 15: 53: 2009-11-10 15:46:22.161 to 2009-11-18 10:58:17.674 16: 55: 2009-11-25 23:44:19.069 to 2009-12-03 11:26:37.151 17: 56: 2009-12-03 08:22:31.792 to 2009-12-10 22:03:52.604 18: 57: 2009-12-10 18:55:33.969 to 2009-12-18 06:58:47.247 19: 72: 2010-04-04 11:17:28.386 to 2010-04-12 09:13:51.008 20: 74: 2010-04-19 14:09:01.851 to 2010-04-27 03:44:14.913 21: 77: 2010-05-12 01:33:51.796 to 2010-05-19 20:43:01.583 22: 78: 2010-05-19 17:33:48.047 to 2010-05-27 13:02:03.396 23: 103: 2010-11-26 07:56:05.324 to 2010-12-04 04:11:44.879 24: 187a: 2012-11-21 00:17:13.430 to 2012-11-25 00:40:26.707 25: 188b: 2012-12-03 12:46:18.859 to 2012-12-08 00:44:50.846 26: 206a: 2013-05-13 23:15:27.433 to 2013-05-17 12:19:58.215 27: 207b: 2013-05-26 12:21:08.868 to 2013-05-30 23:14:44.989 28: For the first two and a half years of science operations (through Orbit 127), IBEX's orbital period was ~7.5 days and the spin axis was repointed once each orbit (around perigee), leading to bands of sky viewing centered 7.5 degree apart. In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step (ESA1) in exchange for doubling the statistical sampling of ESA3 (center energy ~1.1 keV).

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2008-2017. 2: This data set is from the Park et al. (2015) subset of Release 9 for IBEX-Lo Heavy Neutral Maps data for combination and averaging of six-month maps 1-6 into three-year maps for each energy channel during 2008-2011 in the form of counting rates and supporting parameters. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles from the measured direct events identified as 'Oxygen', which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns (Park et al. 2015). Because there are no sputtering, corrections, the 'Oxygen'.events may include O, Ne, and other heavier elements. The single O maps are produced by Pipeline code. There are energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from this part ofRelease 9 are given in the following journal publication: 4: J. Park et al., Statistical Analysis of the Heavy Neutral Atoms Measured by IBEX. The Astrophysical Journal Supplement Series, 220:34 (13pp), 2015 October. http://dx.doi.org/10.1088/0067-0049/220/2/34 5. The following list associates Release 9 map numbers (1-6) with mission year (1-3), orbits (11-150a), and dates (12/25/2008-12/24/2011): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 6: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 7: This particular data set, denoted in the original ascii files as comb-ot-m1m6 includes combined IBEX-Lo heavy neutral pixel maps data (map1 + map2 + map3 + map4 + map5 + map6) from all directions
- Modification History
The Release 9 data contains Maps 1 - 6. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

(2015) subset of Release 9 for IBEX-Lo Heavy Neutral Maps (6 months-cadence) data from combined odd maps (1,3,5) during 2008-2011 in the form of counting rates and supporting parameters. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles from the measured direct events identified as 'Oxygen', which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns (Park et al. 2015). Because there are no sputtering, corrections, the 'Oxygen'.events may include O, Ne, and other heavier elements. The single O maps are produced by Pipeline code. There are energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from this part ofRelease 9 are given in the following journal publication: 4: J. Park et al., Statistical Analysis of the Heavy Neutral Atoms Measured by IBEX. The Astrophysical Journal Supplement Series, 220:34 (13pp), 2015 October. http://dx.doi.org/10.1088/0067-0049/220/2/34 5. The following list associates Release 9 map numbers (1-6) with mission year (1-3), orbits (11-150a), and dates (12/25/2008-12/24/2011): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 6: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 7: This particular data set, denoted in the original ascii files as comb-ot-m1m3m5 includes combined IBEX-Lo heavy neutral pixel odd maps data (map1 + map3 + map5) from all directions
- Modification History
The Release 9 data contains Maps 1 - 6. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

(2015) subset of Release 9 for IBEX-Lo Heavy Neutral Maps, mostly of oxygen, averaged over three years, 2008-2011, from IBEX-Lo maps 1 ... 6. There are four types of maps derived from different statistical filtering approaches: signal/noise filtering, confidence limit method (CLM), cluster analysis method (CLM), and CLUSTER with signal/noise filtering, all as described in Park et al. (2015). Map data for the first two approaches are in counts/second and for the last two in counts/hour (Cluster ID). 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles from the measured direct events identified as 'Oxygen', which are registered between 50 ns and 100 ns in TOF2; i.e. 50ns<=TOF2<=100ns (Park et al. 2015).

In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step (ESA1) in exchange for doubling the statistical sampling of ESA3 (center energy ~1.1 keV). 29: Interstellar He represents a key sample of interstellar matter that, due to its high first ionization potential, survives the journey from beyond our solar system's heliospheric boundaries to Earth. Ongoing analysis of interstellar neutral (ISN) He atoms by the Interstellar Boundary Explorer (IBEX) has resulted in a growing sophistication in our understanding of local interstellar flow. A key feature of the IBEX observations near perihelion of the ISN trajectories is a narrow 'tube' of approximately degenerate interstellar parameters. These degenerate solutions provide a tightly coupled relationship between interstellar flow longitude and latitude, speed, and temperature. However, IBEX analysis resulting in a specific solution for inflow longitude, inflow speed, temperature and inflow latitude was accompanied with a sizeable uncertainty along the parameter tube. Here, we use the three-step method to find the interstellar parameters: 1) the ISN He peak rate in ecliptic longitude determines uniquely a relation (as part of the tube in parameter space) between the longitude lambda-ISN-8 and the speed VISN-8 of the He ISN flow at infinity; 2) the ISN He peak latitude (on the great circle swept out in each spin) is compared to simulations to derive unique values for lambda-ISN-8 and VISN-8 along the parameter tube; 3) the angular width of the He flow distributions as a function of latitude is used to derive the interstellar He temperature. For simulated peak latitudes, we use a relatively new analytical tool that traces He atoms from beyond the termination shock into the position of IBEX and incorporates the detailed response function of IBEX-Lo. By varying interstellar parameters along the IBEX parameter tube, we find the specific parameters that minimize the chi-square difference between observations and simulations. The new computational tool for simulating neutral atoms through the integrated IBEX-Lo response function makes no assumptions or expansions with respect to spin axis pointing or frame of reference. Thus, we are capable of moving beyond closed form approximations and utilize observations of interstellar He during the complete 5 year period from 2009 to 2013 when the primary component of interstellar He is most prominent. Chi-square minimization of simulations compared to observations results in a He ISN flow longitude 75.6 degrees +-1.40 degrees, latitude -5.12 degrees +-0.27 degrees , speed 25.4 +-1.1 km/s, and temperature 8000 +-1300 K, where the uncertainties are related and apply along the IBEX parameter tube. This paper also provides documentation for a new release of ISN data and associated model runs'IBEX data used in the Schwadron et al. 2015 analysis to compute interstellar He parameters. Data are included for each position along the parameter tube as defined by the inflow speed. The inflow speed is given by the filename (i.e. runex-22.888889.txt means 22.9 km/s inflow speed).

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (6 months-cadence) IBEX-Lo map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes without any corrections (nocg) for spacecraft motion (Compton-Getting) and ENA survival probability (nosp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_mapN for N=1,14, includes pixel map data from all directions (omnidirectional), no CG, no SP, 6 month cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (7-year-average of 6-month-cadence maps) IBEX-Lo map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes without any corrections for spacecraft motion (nocg) (Compton-Getting) and with no applied ENA survival probability correction (nosp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_single, includes pixel map data from all directions (omnidirectional), no CG, SP, 7 year cadence.
- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Modification History
The Release 10 data extend through Map 14 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 15 releases of IBEX-HI and/or IBEX-LO data covering 2009-2017. 2: This data set is from the Release 10 (7-year-average of 6-month-cadence maps) IBEX-Lo map data for the first seven years, 2009-2015, in the form of omnidirectional fluxes without any corrections for spacecraft motion (nocg) (Compton-Getting) but with the applied ENA survival probability correction (sp) between 1 and 100 AU. 3: The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 5-8 in numerical data form. Energy channels 5-8 have FWHM center-point energies at 0.209, 0.439, 0.872, 1.821 keV, respectively. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: S.A. Fuselier et al., The IBEX-Lo Sensor. Space Sci Rev (2009) 146: 117...147; DOI 10.1007/s11214-009-9495-8 5: https://link.springer.com/article/10.1007/s11214-009-9495-8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 10 map numbers (1-14) with mission year (1-7), orbits (11-310b), and dates (12/25/2008-12/23/2015): Map 1: year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_tabular_single, includes pixel map data from all directions (omnidirectional), no CG, SP, 7 year cadence.

In June 2011, over Orbits 128 and 129, IBEX was maneuvered into a previously unknown, long-term stable lunar synchronous orbit with apogee still ~50 RE (McComas et al. 2011a). Since then, IBEX's orbital period has been ~9.1 days (one-third of the lunar sidereal period of 27.3 days). Orbit numbers from 130 onward are split into two segments, 'a' and 'b.' Furthermore, starting in orbit segment 184a, the IBEX team modified the IBEX-Hi energy step sequence and eliminated the lowest energy step (ESA1) in exchange for doubling the statistical sampling of ESA3 (center energy ~1.1 keV).

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of omni-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 17 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_cg_hb_N for N=2009-2019, includes pixel map data from all directions (omnidirectional), CG, no SP, 1 year cadence.
- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 17 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_noSP_ram_cg_hb_N for N=2009-2019, includes pixel map data from ram direction, CG, no SP, 1 year cadence.
- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of antiram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and with correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 17 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_tabular_antiram_cg_hb_N for N=2009-2019, includes pixel map data from antiram direction, CG, SP, 1 year cadence.
- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of omni-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and with correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7. The following list associates Release 17 map numbers (1-22) with mission year (1-9), orbits (11-471b), and dates (12/25/2008-12/26/2019): Map 1: Map2009A, year 1, orbits 11-34, dates 12/25/2008-06/25/2009 Map 2: Map2009B, year 1, orbits 35-58, dates 06/25/2009-12/25/2009 Map 3: Map2010A, year 2, orbits 59-82, dates 12/25/2009-06/26/2010 Map 4: Map2010B, year 2, orbits 83-106, dates 06/26/2010-12/26/2010 Map 5: Map2011A, year 3, orbits 107-130a, dates 12/26/2010-06/25/2011 Map 6: Map2011B, year 3, orbits 130b-150a, dates 06/25/2011-12/24/2011 Map 7: Map2012A, year 4, orbits 150b-170a, dates 12/24/2011-06/22/2012 Map 8: Map2012B, year 4, orbits 170b-190b, dates 06/22/2012-12/26/2012 Map 9: Map2013A, year 5, orbits 191a-210b, dates 12/26/2012-06/26/2013 Map 10: Map2013B, year 5, orbits 211a-230b, dates 06/26/2013-12/26/2013 Map 11: Map2014A, year 6, orbits 231a-250b, dates 12/26/2013-06/26/2014 Map 12: Map2014B, year 6, orbits 251a-270b, dates 06/26/2014-12/24/2014 Map 13: Map2015A, year 7, orbits 271a-290b, dates 12/24/2014-06/24/2015 Map 14: Map2015B, year 7, orbits 291a-310b, dates 06/24/2015-12/23/2015 Map 15: Map2016A, year 8, orbits 311a-330b, dates 12/24/2015 . 06/23/2016 Map 16: Map2016B, year 8, orbits 331a-351a, dates 06/24/2016 . 12/26/2016 Map 17: Map2017A, year 9, orbits 351b-371a, dates 12/26/2016 . 06/24/2017 Map 18: Map2017B, year 9, orbits 371b-391a, dates 06/25/2017 . 12/25/2017 Map 19: Map2018A, year 10, orbits 391b-411b, dates 12/25/2017 . 06/28/2018 Map 20: Map2018B, year 10, orbits 412a-431b, dates 06/29/2018 . 12/26/2018 Map 21: Map2019A, year 11, orbits 432a-451b, dates 12/27/2018 . 06/27/2019 Map 22: Map2019B, year 11, orbits 452a-471b, dates 06/28/2019 . 12/26/2019 8: The energy resolution is delta-E/E = 0.8 for all channels: Energy channel 1: center energy = 0.015 keV Energy channel 2: center energy = 0.029 keV Energy channel 3: center energy = 0.055 keV Energy channel 4: center energy = 0.11 keV Energy channel 5: center energy = 0.209 keV Energy channel 6: center energy = 0.439 keV Energy channel 7: center energy = 0.872 keV Energy channel 8: center energy = 1.821 keV 9: This particular data set, denoted in the original ascii files as lvset_h_tabular_cg_hb_N for N=2009-2019, includes pixel map data from all directions (omnidirectional), CG, SP, 1 year cadence.
- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and with correction for ENA survival probability (sp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 16 releases of IBEX-HI and/or IBEX-LO data covering 2009-2019. 2: This data set is from the Release 17 (1 year-cadence) IBEX-Lo map data for the years 2009-2019 in the form of ram-directional ENA (hydrogen) fluxes with no Compton-Getting correction (nocg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Lo energy bands 1-8 in numerical data form. Energy channels 1-8 have FWHM center-point energies at 0.015, 0.029, 0.055, 0.11, 0.209, 0.439, 0.872, 1.821 keV, respectively. 4: Details of the data and enabled science from Release 10 are given in the following journal publication: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), 5: http://doi.org/10.3847/1538-4365/aa66d8 6. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. noSP - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. 7.

- Modification History
The Release 17 data extend through Map 22 and contain modications and updates of Maps 1-2 from Release 2, Maps 1-6 from Release 4, and Maps 1-10 from Release 7, maps 1-14 from Release 10, maps 15-22 from Release 16. The present CDF data set was converted from the originally archived data in ascii list format but otherwise includes no changes in the data. The original data are given in 30 rows for Solar Ecliptic Latitude and 60 columns for Solar Ecliptic East Longitude. The accompanying documentation described the row latitude data as starting from the north Ecliptic pole (+90 degrees) and decreasing in value to the south Ecliptic pole (-90 degrees). During preparation of the data set in CDF format, SPDF discovered that the correct order was increasing from row 1 for the South Ecliptic pole to row 30 for the north Ecliptic pole. East longitude is defined correctly for the column order but we have instead used west longitude to better represent the outward-looking viewpoint from IBEX to the outer heliosphere as typically used in IBEX team plots.

- Description
1: The Interstellar Boundary Explorer (IBEX) has operated in space since 2008 updating our knowledge of the outer heliosphere and its interaction with the local interstellar medium. Start-time: 2008-12-25. There are currently 18 releases of IBEX-HI and IBEX-LO data covering 2009-2022. 2: This data set is from the Release 18 (1 year-cadence) IBEX-Hi map data for the years 2009-2022 in the form of antiramdirectional ENA (hydrogen) fluxes with Compton-Getting correction (cg) of flux spectra for spacecraft motion and no correction for ENA survival probability (nosp) between 1 and 100 AU. 3. The data consist of all-sky maps in Solar Ecliptic Longitude (east and west) and Latitude angles for ENA (hydrogen) fluxes from IBEX-Hi energy bands 2-6 in numerical data form. Energy channels 2-6 have FWHM ranges of 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV, respectively. The corresponding center-point energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Details of the data and enabled science from Release 10 are given in the following journal publication: 4: McComas, D. J., et al. (2017), Seven Years of Imaging the Global Heliosphere with IBEX, Astrophys. J. Supp. Ser., 229(2), 41 (32 pp.), http://doi.org/10.3847/1538-4365/aa66d8 5. The following codes are used to define dataset types: cg = Compton-Getting corrections have been applied to the data to account for the speed of the spacecraft relative to the direction of arrival of the ENAs. nocg = no Compton-Getting corrections sp = survival probability corrections have been applied to the data to account for the loss of ENAs due to radiation pressure, photoionization and ionization via charge exchange with solar wind protons as they stream through the heliosphere. This correction scales the data out from IBEX at 1 AU to ~100 AU. In the original data this mode is denoted as Tabular. nosp - no survival probability corrections have been applied to the data. omni = data from all directions. ram = data was collected when the spacecraft was ramming into the incoming ENAs. antiram = data was collected when the spacecraft was moving away from the incoming ENAs. mono = mono-energy Compton-Getting corrected maps. 6.

- ICON_L2-1_MIGHTI-A_LOS-WIND-GREEN
- Description
ICON explores the boundary between Earth and space - the ionosphere - to understand the physical connection between our world and the immediate space environment around us. Visit 'http://icon.ssl.berkeley.edu' for more details.
- Data Variable Descriptions
- Fringe amplitude profile [ICON_L21_Fringe_Amplitude]
An approximate volume emission rate (VER) profile in arbitrary units. Technically this a profile of the amplitude of the fringes, which has a dependence on thermospheric temperature and background emission. Thus, it does not truly represent volume emission rate. However, it is a useful proxy. The units are arbitrary, but an attempt has been made to cross-calibrate MIGHTI-A with MIGHTI-B. In contrast to the wind inversion, which is nonlinear due to the phase extraction step, the amplitude inversion is purely linear. The Level 1 interferogram is analyzed to obtain a single brightness value per zenith angle, and this is inverted with the distance matrix to obtain a value of the amplitude per altitude.
- Fringe amplitude error profile [ICON_L21_Fringe_Amplitude_Error]
The statistical (1-sigma) error in the fringe amplitude. As with the wind, systematic errors are not included, but can arise from sources such as horizontal gradients and inaccurate calibration.
- Line-of-sight horizontal wind profile. A positive wind is towards MIGHTI. [ICON_L21_Line_of_Sight_Wind]
The wind is the primary data product in this file. This variable contains the projection of the horizontal wind (at the tangent point) onto the line of sight direction. An entire altitude profile is observed simultaneously. An onion-peeling inversion is used on the raw observations to remove the effects of the integration along the line of sight. The line-of-sight wind is defined such that a positive value indicates motion towards the spacecraft. This direction is given by the Line_of_Sight_Azimuth variable. It is assumed that the vertical wind is zero, but even large vertical winds (~100 m/s) do not significantly affect this data product, since the line of sight is nearly horizontal everywhere. It should be noted that while this measurement is ascribed to a particular latitude, longitude and altitude, it is actually an average over many hundreds of kilometers horizontally, and 2.5-30 kilometers vertically (depending on the binning). See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using Doppler shifts to determine winds. The zero wind phase is defined as the measured interference fringe phase that corresponds to the rest wavelength of the emission. For this initial data release, the zero wind phase has been determined by comparing a 60-day average of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades of previous wind measurements. At each time and location of a MIGHTI measurement, the MIGHTI measurement is simulated by integrating HWM14 along the line of sight, weighted by the observed volume emission rate as determined by the measured fringe amplitude profile. The 60-day-average difference between the measured and simulated phases is taken as the zero wind phase. This is done separately for each sensor (A and B), for each color (red and green), for each mode (day and night), and for each row (i.e., each altitude). This approach to determining the zero wind phase is analogous to the approach taken for the UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a long-term average of the meridional wind is zero. Although the long-term average altitude profile is constrained to match HWM14 in this initial MIGHTI data release, measured variations in time, latitude, longitude, and from day to day are retained using this approach. A future data release will leverage ICON's unique 'zero wind maneuver' to determine an independent zero wind phase.
- Line-of-sight wind precision (1 sample) [ICON_L21_Line_of_Sight_Wind_Precision_1_Sample]
Various sources of error in MIGHTI winds are quantified with 1-sigma estimates and organized by their temporal persistence. These error sources are nearly uncorrelated with each other and can thus be added in quadrature. Users are encouraged to contact the MIGHTI team for assistance with error propagation.

Various sources of error in MIGHTI winds are quantified with 1-sigma estimates and organized by their temporal persistence. These error sources are nearly uncorrelated with each other and can thus be added in quadrature. Users are encouraged to contact the MIGHTI team for assistance with error propagation.
- Line-of-sight wind accuracy [ICON_L21_Line_of_Sight_Wind_Accuracy]
Various sources of error in MIGHTI winds are quantified with 1-sigma estimates and organized by their temporal persistence. These error sources are nearly uncorrelated with each other and can thus be added in quadrature. Users are encouraged to contact the MIGHTI team for assistance with error propagation.
- Line-of-sight horizontal wind error profile [ICON_L21_Line_of_Sight_Wind_Error]
The statistical (1-sigma) error in the line-of-sight wind. This is usually dominated by shot noise, but also includes the effects of dark and read noise, as well as calibrations errors (e.g., the zero wind calibration), and spacecraft pointing error (which affects the uncertainty in removing the spacecraft velocity from the observed velocity). Other systematic errors or biases may exist (e.g., the effect of gradients along the line of sight) which are not included in this variable. Errors in daily calibrations may create systematic patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59 UT) but change from day to day.
- Relative volume emission rate (VER) profile [ICON_L21_Relative_VER]
The volume emission rate (VER) obtained by scaling the fringe amplitude by a calibration factor. Pre-flight calibrations and on-orbit comparisons with ground-based instruments are used to determine the best possible calibration. The fringe amplitude has a dependence on temperature, which is corrected using the MSIS model. Because the on-orbit calibration is uncertain, and because the MSIS temperature correction is not perfect, caution should be exercised when absolute calibration is required, or when comparisons are being made between samples at different temperatures. Please contact the MIGHTI team before performing any studies that require absolute calibration. The statistical (1-sigma) error for this variable is provided in the variable ICON_..._Relative_VER_Error, though it is expected that systematic calibration errors dominate the total error. See the Fringe_Amplitude variable for a discussion of the inversion.
- Relative volume emission rate (VER) error profile [ICON_L21_Relative_VER_Error]
The statistical (1-sigma) error in the relative VER estimate. This error arises mostly from shot noise. Importantly, it is expected that systematic errors (e.g., calibration errors) dominate the total error, but they are not included in this variable.
- A quantification of the volume emission rate (VER) quality, from 0 (Bad) to 1 (Good) [ICON_L21_VER_Quality]
A quantification of the overall quality of the VER data. While the intent is that the variable VER_Error accurately characterizes the statistical error in the wind data, it is possible that systematic errors are present, or that the statistical error estimation is not accurate. If it is suspected that this is the case, the quality will be less than 1.0. If the data are definitely unusable, the the quality will be 0.0 and the sample will be masked. Users should exercise caution when the quality is less than 1.0. This parameter can currently take 3 values: 0.0 (Bad), 0.5 (Caution), 1.0 (Good)

The line-of-sight wind is defined such that a positive value indicates motion towards the spacecraft. This direction is given by the Line_of_Sight_Azimuth variable. It is assumed that the vertical wind is zero, but even large vertical winds (~100 m/s) do not significantly affect this data product, since the line of sight is nearly horizontal everywhere. It should be noted that while this measurement is ascribed to a particular latitude, longitude and altitude, it is actually an average over many hundreds of kilometers horizontally, and 2.5-30 kilometers vertically (depending on the binning). See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using Doppler shifts to determine winds. The zero wind phase is defined as the measured interference fringe phase that corresponds to the rest wavelength of the emission. For this initial data release, the zero wind phase has been determined by comparing a 60-day average of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades of previous wind measurements. At each time and location of a MIGHTI measurement, the MIGHTI measurement is simulated by integrating HWM14 along the line of sight, weighted by the observed volume emission rate as determined by the measured fringe amplitude profile. The 60-day-average difference between the measured and simulated phases is taken as the zero wind phase. This is done separately for each sensor (A and B), for each color (red and green), for each mode (day and night), and for each row (i.e., each altitude). This approach to determining the zero wind phase is analogous to the approach taken for the UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a long-term average of the meridional wind is zero. Although the long-term average altitude profile is constrained to match HWM14 in this initial MIGHTI data release, measured variations in time, latitude, longitude, and from day to day are retained using this approach. A future data release will leverage ICON's unique 'zero wind maneuver' to determine an independent zero wind phase.
- Line-of-sight wind accuracy [ICON_L21_Line_of_Sight_Wind_Accuracy]
Various sources of error in MIGHTI winds are quantified with 1-sigma estimates and organized by their temporal persistence. These error sources are nearly uncorrelated with each other and can thus be added in quadrature. Users are encouraged to contact the MIGHTI team for assistance with error propagation.
- Line-of-sight horizontal wind error profile [ICON_L21_Line_of_Sight_Wind_Error]
The statistical (1-sigma) error in the line-of-sight wind. This is usually dominated by shot noise, but also includes the effects of dark and read noise, as well as calibrations errors (e.g., the zero wind calibration), and spacecraft pointing error (which affects the uncertainty in removing the spacecraft velocity from the observed velocity). Other systematic errors or biases may exist (e.g., the effect of gradients along the line of sight) which are not included in this variable. Errors in daily calibrations may create systematic patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59 UT) but change from day to day.

- Relative volume emission rate profile [ICON_L21_Relative_VER]
The volume emission rate (VER) obtained by scaling the fringe amplitude by a calibration factor. Pre-flight calibrations and on-orbit comparisons with ground-based instruments are used to determine the best possible calibration. The fringe amplitude has a dependence on temperature, which is corrected using the MSIS model. Because the on-orbit calibration is uncertain, and because the MSIS temperature correction is not perfect, caution should be exercised when absolute calibration is required, or when comparisons are being made between samples at different temperatures. Please contact the MIGHTI team before performing any studies that require absolute calibration. The statistical (1-sigma) error for this variable is provided in the variable ICON_..._Relative_VER_Error, though it is expected that systematic calibration errors dominate the total error. See the Fringe_Amplitude variable for a discussion of the inversion.

A quantification of the overall quality of the VER data. While the intent is that the variable VER_Error accurately characterizes the statistical error in the wind data, it is possible that systematic errors are present, or that the statistical error estimation is not accurate. If it is suspected that this is the case, the quality will be less than 1.0. If the data are definitely unusable, the the quality will be 0.0 and the sample will be masked. Users should exercise caution when the quality is less than 1.0. This parameter can currently take 3 values: 0.0 (Bad), 0.5 (Caution), 1.0 (Good)

- Fringe amplitude profile [ICON_L21_Fringe_Amplitude]
An approximate volume emission rate (VER) profile in arbitrary units. Technically this a profile of the amplitude of the fringes, which has a dependence on thermospheric temperature and background emission. Thus, it does not truly represent volume emission rate. However, it is a useful proxy. The units are arbitrary, but an attempt has been made to cross-calibrate MIGHTI-A with MIGHTI-B. In contrast to the wind inversion, which is nonlinear due to the phase extraction step, the amplitude inversion is purely linear. The Level 1 interferogram is analyzed to obtain a single brightness value per zenith angle, and this is inverted with the distance matrix to obtain a value of the amplitude per altitude.

- Fringe Amplitude [ICON_L22_Fringe_Amplitude]
An approximate volume emission rate (VER) profile in arbitrary units, estimated by combining MIGHTI-A and MIGHTI-B data. Technically this is not the VER, but rather the amplitude of the fringes, which has a dependence on thermospheric temperature and background emission. Thus, it does not truly represent volume emission rate. However, it is a useful proxy. The units are arbitrary, as the fringe amplitudes are not calibrated. See also variables Fringe_Amplitude_Relative_Difference, Fringe_Amplitude_A, and Fringe_Amplitude_B.
- Error in the fringe amplitude estimate [ICON_L22_Fringe_Amplitude_Error]
The statistical (1-sigma) error in the fringe amplitude estimate, propagated from error in the MIGHTI-A and MIGHTI-B inversions. The units are arbitrary, as the fringe amplitudes are not absolutely calibrated. Systematic errors, such as those arising from airglow gradients or cross-calibration, are not included in this variable, but are probably the dominant source of total error.
- Magnetic field-aligned component of the wind [ICON_L22_Magnetic_Field_Aligned_Wind]
The component of the wind in the direction of the magnetic field line, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The coordinate system used here is orthogonal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Magnetic meridional component of the wind [ICON_L22_Magnetic_Meridional_Wind]
The component of the wind in the magnetic meridional direction, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The magnetic meridional unit vector is orthogonal to the magnetic field line but within the plane of the magnetic meridian (defined by the apex of the field line and its footpoint). At the magnetic equator, the meridional direction points up, while away from the equator it has a poleward component (north in the northern hemisphere, south in the southern hemisphere). Note that in some ion-neutral coupling models, a definition of magnetic meridional is often used that is horizontal (i.e., perpendicular to gravity) and generally northward. The definition used here is perpendicular to B and thus has primarily a vertical component at ICON latitudes. Note also that the definition of magnetic meridional and zonal used here differs from quasi-dipole and apex coordinate bases. The coordinate system used here is orthonormal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Magnetic zonal component of the wind [ICON_L22_Magnetic_Zonal_Wind]
The component of the wind in the magnetic zonal direction, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). At the magnetic equator, the zonal direction points horizontally, while away from the equator it can have a slightly vertical component. Note that the definition of magnetic meridional and zonal used here differs from quasi-dipole and apex coordinate bases. The coordinate system used here is orthonormal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Meridional component of the horizontal wind. Positive Northward. [ICON_L22_Meridional_Wind]
The zonal (positive eastward) and meridional (positive northward) winds are the primary data product in this file. They are defined on a grid with dimensions of time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the red channel). The altitude, time, latitude and longitude corresponding to each point in the grid are given by other variables in this file. It should be noted that while each measurement is ascribed to a particular latitude, longitude, altitude, and time, it is actually an average over many hundreds of kilometers horizontally and 2.5-30 kilometers vertically (depending on the binning). It also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B measurements used for each point. See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using Doppler shifts to determine winds. The zero wind phase is defined as the measured interference fringe phase that corresponds to the rest wavelength of the emission. For this initial data release, the zero wind phase has been determined by comparing a 60-day average of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades of previous wind measurements. At each time and location of a MIGHTI measurement, the MIGHTI measurement is simulated by integrating HWM14 along the line of sight, weighted by the observed volume emission rate as determined by the measured fringe amplitude profile. The 60-day-average difference between the measured and simulated phases is taken as the zero wind phase. This is done separately for each sensor (A and B), for each color (red and green), for each mode (day and night), and for each row (i.e., each altitude). This approach to determining the zero wind phase is analogous to the approach taken for the UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a long-term average of the meridional wind is zero. Although the long-term average altitude profile is constrained to match HWM14 in this initial MIGHTI data release, measured variations in time, latitude, longitude, and from day to day are retained using this approach. A future data release will leverage ICON's unique 'zero wind' 'maneuver' to determine an independent zero wind phase.

- Error in the meridional wind estimate. [ICON_L22_Meridional_Wind_Error]
The statistical (1-sigma) error in the meridional wind, propagated from the error in the L2.1 (line-of-sight wind) files. This is usually dominated by shot noise in the detectors, but also includes the effects of dark and read noise, as well as calibrations errors (e.g., the zero wind calibration), and spacecraft pointing error (which affects the uncertainty in removing the spacecraft velocity from the observed velocity). Other systematic errors or biases may exist (e.g., the effect of gradients along the line of sight) which are not included in this variable.Errors in daily calibrations may create systematic patterns in winds that are constant for an entire 24 hour period (00:00 - 23:59 UT) but change from day to day.

- ICON orbit ascending/descending flag [ICON_L22_Orbit_Node]
A flag indicating whether ICON is in the ascending (0) or descending (1) part of the orbit. For some grid points, samples from MIGHTI-A are on the descending part of the orbit, while samples from MIGHTI-B are ascending. In these cases an interpolated value is used (between 0 and 1).
- ICON orbit number [ICON_L22_Orbit_Number]
The ICON orbit number corresponding to each grid point. This is usually an integer, but when samples from two different orbits are used, an interpolated (fractional) value is used.
- Relative volume emission rate [ICON_L22_Relative_VER]
The volume emission rate (VER) obtained by averaging the VER from MIGHTI-A and MIGHTI-B, which is obtained by scaling the fringe amplitude by a calibration factor, as described in Data Product 2.1. Pre-flight calibrations and on-orbit comparisons with ground-based instruments are used to determine the best possible calibration. The fringe amplitude has a dependence on temperature, which is corrected using the MSIS model. Because the on-orbit calibration is uncertain, and because the MSIS temperature correction is not perfect, caution should be exercised when absolute calibration is required, or when precise comparisons are being made between samples at very different temperatures. Please contact the MIGHTI team before performing any studies that require absolute calibration. The statistical (1-sigma) error for this variable is provided in the variable ICON_..._Relative_VER_Error, though it is expected that systematic calibration errors dominate the total error.
- Error in VER estimate (statistical) [ICON_L22_Relative_VER_Error]
The statistical (1-sigma) error in the relative VER estimate, propagated from error in the MIGHTI-A and MIGHTI-B inversions. This error arises mostly from shot noise. Importantly, it is expected that systematic errors (e.g., calibration errors) dominate the total error, but they are not included in this variable.
- A quantification of the VER data quality, from 0 (Bad) to 1 (Good) [ICON_L22_VER_Quality]
A quantification of the overall quality of the VER data. While the intent is that the XXX_VER_Error variable accurately characterizes the statistical error in the VER data, it is possible that systematic errors are present, or that the statistical error estimation is not accurate. If it is suspected that this is the case, the quality will be less than 1.0. If the data are definitely unusable, the quality will be 0.0 and the sample will be masked. Users should exercise caution when the quality is less than 1.0. Currently, the quality can take values of 0 (Bad), 0.5 (Caution), or 1 (Good).
- A quantification of the wind data quality, from 0 (Bad) to 1 (Good) [ICON_L22_Wind_Quality]
A quantification of the overall quality of the wind data. While the intent is that the XXX_Wind_Error variable accurately characterizes the statistical error in the wind data, it is possible that systematic errors are present, or that the statistical error estimation is not accurate. If this is suspected to be the case, the quality will be less than 1.0. If the data are definitely unusable, the quality will be 0.0 and the sample will be masked. Users should exercise caution when the quality is less than 1.0. Currently, the quality can take values of 0 (Bad), 0.5 (Caution), or 1 (Good).
- Zonal component of the horizontal wind. Positive Eastward. [ICON_L22_Zonal_Wind]
The zonal (positive eastward) and meridional (positive northward) winds are the primary data product in this file. They are defined on a grid with dimensions of time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the red channel). The altitude, time, latitude and longitude corresponding to each point in the grid are given by other variables in this file. It should be noted that while each measurement is ascribed to a particular latitude, longitude, altitude, and time, it is actually an average over many hundreds of kilometers horizontally and 2.5-30 kilometers vertically (depending on the binning). It also assumes stationarity over the 5-8 minutes between the MIGHTI-A and B measurements used for each point. See Harding et al. [2017, doi:10.1007/s11214-017-0359-3] for a more complete discussion of the inversion algorithm. Knowledge of the 'zero wind phase' is needed for any instrument using Doppler shifts to determine winds. The zero wind phase is defined as the measured interference fringe phase that corresponds to the rest wavelength of the emission. For this initial data release, the zero wind phase has been determined by comparing a 60-day average of MIGHTI data to a 60-day average of the empirical Horizontal Wind Model 2014 (HWM14, Drob et al., 2015, doi:10.1002/2014EA000089), which is a fit to decades of previous wind measurements. At each time and location of a MIGHTI measurement, the MIGHTI measurement is simulated by integrating HWM14 along the line of sight, weighted by the observed volume emission rate as determined by the measured fringe amplitude profile. The 60-day-average difference between the measured and simulated phases is taken as the zero wind phase. This is done separately for each sensor (A and B), for each color (red and green), for each mode (day and night), and for each row (i.e., each altitude). This approach to determining the zero wind phase is analogous to the approach taken for the UARS/HRDI instrument (Hays et al., 1992, doi:10.1016/0032-0633(92)90119-9), which assumed that a long-term average of the meridional wind is zero. Although the long-term average altitude profile is constrained to match HWM14 in this initial MIGHTI data release, measured variations in time, latitude, longitude, and from day to day are retained using this approach. A future data release will leverage ICON's unique 'zero wind maneuver' to determine an independent zero wind phase.

- Data Variable Descriptions
- Fringe Amplitude [ICON_L22_Fringe_Amplitude]
An approximate volume emission rate (VER) profile in arbitrary units, estimated by combining MIGHTI-A and MIGHTI-B data. Technically this is not the VER, but rather the amplitude of the fringes, which has a dependence on thermospheric temperature and background emission. Thus, it does not truly represent volume emission rate. However, it is a useful proxy. The units are arbitrary, as the fringe amplitudes are not calibrated. See also variables Fringe_Amplitude_Relative_Difference, Fringe_Amplitude_A, and Fringe_Amplitude_B.
- Error in the fringe amplitude estimate [ICON_L22_Fringe_Amplitude_Error]
The statistical (1-sigma) error in the fringe amplitude estimate, propagated from error in the MIGHTI-A and MIGHTI-B inversions. The units are arbitrary, as the fringe amplitudes are not absolutely calibrated. Systematic errors, such as those arising from airglow gradients or cross-calibration, are not included in this variable, but are probably the dominant source of total error.
- Magnetic field-aligned component of the wind [ICON_L22_Magnetic_Field_Aligned_Wind]
The component of the wind in the direction of the magnetic field line, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The coordinate system used here is orthogonal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Magnetic meridional component of the wind [ICON_L22_Magnetic_Meridional_Wind]
The component of the wind in the magnetic meridional direction, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). The magnetic meridional unit vector is orthogonal to the magnetic field line but within the plane of the magnetic meridian (defined by the apex of the field line and its footpoint ). At the magnetic equator, the meridional direction points up, while away from the equator it has a poleward component (north in the northern hemisphere, south in the southern hemisphere). Note that in some ion-neutral coupling models, a definition of magnetic meridional is often used that is horizontal (i.e., perpendicular to gravity) and generally northward. The definition used here is perpendicular to B and thus has primarily a vertical component at ICON latitudes. Note also that the definition of magnetic meridional and zonal used here differs from quasi-dipole and apex coordinate bases. The coordinate system used here is orthonormal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Magnetic zonal component of the wind [ICON_L22_Magnetic_Zonal_Wind]
The component of the wind in the magnetic zonal direction, assuming vertical winds are negligible. This variable is calculated by taking the geographic zonal and meridional wind (the primary data products in this file) and expressing the wind vector in a local magnetic coordinate system defined using the Python package OMMBV (.https://github.com/rstoneback/OMMBV). At the magnetic equator, the zonal direction points horizontally, while away from the equator it can have a slightly vertical component. Note that the definition of magnetic meridional and zonal used here differs from quasi-dipole and apex coordinate bases. The coordinate system used here is orthonormal and is identical to the coordinate system used to express the ion drifts in the ICON IVM data product 2.7 (i.e., the variables ICON_L27_Ion_Velocity_Meridional, ICON_L27_Ion_Velocity_Zonal, and ICON_L27_Ion_Velocity_Field_Aligned).
- Meridional component of the horizontal wind. Positive Northward. [ICON_L22_Meridional_Wind]
The zonal (positive eastward) and meridional (positive northward) winds are the primary data product in this file. They are defined on a grid with dimensions of time and altitude, spanning 24 hours and nominally 90-300 km (150-300 km for the red channel).

- Data Variable Descriptions
- Derived A-Band Temperatures [ICON_L23_MIGHTI_A_Temperature]
Derived temperatures from A band by altitude. Temperatures are retrieved from the rotational distribution of emission lines in the O2 A band. The measurement is made at 5 spectral channels. 3 channels measure the A band and 2 others on either side of the band measure a background, which is subtracted from the 3 signal channels. An entire altitude profile is observed simultaneously. An onion-peeling inversion is used on the raw observations to remove the effects of the integration along the line of sight. See Stevens et al. (Space Science Reviews (2018) 214:4. .https://doi.org/10.1007/s11214-017-0434-9). O2 A band spectra are pre-calculated from 100-400 K in 20 K increments based on the HITRAN 2016 database [Gordon et al., JQSRT (2017), 203:3-69.https://doi.org/10.1016/j.jqsrt.06.038] and smoothed filter functions with FWHM of ~2.0 nm. The filter functions are based on Gaussian fits to laboratory measurements and are a function of channel, row (altitude), and column. The fits are separately done for each pixel as a function of peak wavenumber (wavelength), width, and transmittance. For each of the three signal channels the fitted Gaussians are co-added over 51 pixels where the transmittance is largest for a representative filter function for that channel. The transmittances are not absolutely calibrated in photometric units, but the relative transmittance between channels and between detectors is maintained, which allows for the retrieval of temperature at the tangent altitude.
- Bias (systematic) uncertainties in derived temperatures by altitude. [ICON_L23_MIGHTI_A_Temperature_Bias_Uncertainty]
Estimated bias uncertainties in derived temperatures by altitude; aka systematic uncertainties. These uncertainties are present in each temperature profile and are primarily due to 1) a 1 cm-1 uncertainty in the common shift applied to pre-flight laboratory determined filter positions. This uncertainty was tested in the retrieval and a derived fixed uncertainty of 12 K is propagated at all altitudes and 2) the lack of measurements above the top altitude sampled, and altitude dependent, with the topmost altitudes of the retrieval affected the most. The temperature bias uncertainty is found by a root sum square of these two. At most altitudes the estimated bias uncertainty is dominated by the uncertainty in the common shift. The systematic bias is the same at all altitudes for daytime images or nighttime images. However, the bias can be different for daytime images and nighttime images.
- Statistical (1-sigma) uncertainties in derived temperature by altitude. [ICON_L23_MIGHTI_A_Temperature_Statistical_Uncertainty]
Statistical uncertainties (one sigma) in derived temperatures by altitude
- Total uncertainties in derived temperatures by altitude [ICON_L23_MIGHTI_A_Temperature_Total_Uncertainty]
Total uncertainties in derived temperatures by altitude: Here the statistical temperature uncertainty has been linearly added to the estimated temperature bias.
- Derived scaling of O2 A Band to Radiances by altitude. [ICON_L23_MIGHTI_A_ABand_Intensity_Scaled]
Derived common scaling of O2 A Band radiances in the 3 signal channels by altitude. Calculated forward radiances are fit to the observations from each of the three signal channels. The scaling is done at each tangent altitude separately and interatively until a best fit solution is found. The intensity of each signal channel relative to the other two determines the temperature, so the scale factor is unitless. The scaling is derived using pre-calculated spectra from the HITRAN 2016 database [Gordon et al., JQSRT, 203, 3-69 (2017)].
- Uncertainty in Scaling of O2 A Band to Radiances by altitude. [ICON_L23_MIGHTI_A_ABand_Intensity_Scaled_Uncertainty]
Derived uncertainty (1-sigma) in derived common scaling of O2 A Band to emergent intensity by altitude.
- Background Signal by filter by altitude and filter. This has been corrected for flatfield effects across the detector. [ICON_L23_MIGHTI_A_Background_Signal]
Background Signal by altitude and filter. This background is interpolated across the 3 signal channels from two background channels located spectrally on either side of the O2 A band.
- ---> Movie of above [ICON_L23_MIGHTI_A_Background_Signal_M]
Background Signal by altitude and filter. This background is interpolated across the 3 signal channels from two background channels located spectrally on either side of the O2 A band.
- Derived Slope of Subtracted Background. [ICON_L23_MIGHTI_A_Background_Slope]
Derived slope of subtracted background. The slope of the background is saved here for diagnostic purposes.

The three channels measuring the A band overdetermines the temperature such that the wavenumber registration due to any thermal drift of the instrument can be additionally inferred. This is typically fixed with altitude and determined (along with temperature) from the signal originating from the O2 A band as measured from 3 signal channels.

- Data Variable Descriptions
- Derived A-Band Temperatures [ICON_L23_MIGHTI_B_Temperature]
Derived temperatures from A band by altitude. Temperatures are retrieved from the rotational distribution of emission lines in the O2 A band. The measurement is made at 5 spectral channels. 3 channels measure the A band and 2 others on either side of the band measure a background, which is subtracted from the 3 signal channels. An entire altitude profile is observed simultaneously. An onion-peeling inversion is used on the raw observations to remove the effects of the integration along the line of sight. See Stevens et al. (Space Science Reviews (2018) 214:4. .https://doi.org/10.1007/s11214-017-0434-9). O2 A band spectra are pre-calculated from 100-400 K in 20 K increments based on the HITRAN 2016 database [Gordon et al., JQSRT (2017), 203:3-69.https://doi.org/10.1016/j.jqsrt.06.038] and smoothed filter functions with FWHM of ~2.0 nm. The filter functions are based on Gaussian fits to laboratory measurements and are a function of channel, row (altitude), and column. The fits are separately done for each pixel as a function of peak wavenumber (wavelength), width, and transmittance. For each of the three signal channels the fitted Gaussians are co-added over 51 pixels where the transmittance is largest for a representative filter function for that channel. The transmittances are not absolutely calibrated in photometric units, but the relative transmittance between channels and between detectors is maintained, which allows for the retrieval of temperature at the tangent altitude.
- Bias (systematic) uncertainties in derived temperatures by altitude. [ICON_L23_MIGHTI_B_Temperature_Bias_Uncertainty]
Estimated bias uncertainties in derived temperatures by altitude; aka systematic uncertainties. These uncertainties are present in each temperature profile and are primarily due to 1) a 1 cm-1 uncertainty in the common shift applied to pre-flight laboratory determined filter positions. This uncertainty was tested in the retrieval and a derived fixed uncertainty of 12 K is propagated at all altitudes and 2) the lack of measurements above the top altitude sampled, and altitude dependent, with the topmost altitudes of the retrieval affected the most. The temperature bias uncertainty is found by a root sum square of these two. At most altitudes the estimated bias uncertainty is dominated by the uncertainty in the common shift. The systematic bias is the same at all altitudes for daytime images or nighttime images. However, the bias can be different for daytime images and nighttime images.

- Derived scaling of O2 A Band to Radiances by altitude. [ICON_L23_MIGHTI_B_ABand_Intensity_Scaled]
Derived common scaling of O2 A Band radiances in the 3 signal channels by altitude. Calculated forward radiances are fit to the observations from each of the three signal channels. The scaling is done at each tangent altitude separately and interatively until a best fit solution is found. The intensity of each signal channel relative to the other two determines the temperature, so the scale factor is unitless. The scaling is derived using pre-calculated spectra from the HITRAN 2016 database [Gordon et al., JQSRT, 203, 3-69 (2017)].

- Milliseconds since 1980-01-06 00:00:00 TAI (coincident with UTC) at middle of reading. [ICON_L27_GPS_Epoch]
Milliseconds since 1980-01-06 00:00:00 TAI (coincident with UTC) at middle of reading. Time is generated from the time-code at byte 1015 of the IVM packet minus the time sync at byte 1019 of the IVM packet. This is the GPS time at the start of the integration period. The integration period is assumed to be 4 seconds so the center time is 2 seconds after that. The formula is (time-code * 1000ms) + 2000ms - (16 * time sync / 1000) in GPS milliseconds then converted to UTC time. See the UTD 206-024 Rev A document. Time may be delayed by up to 10 ms due to FSW polling delay. Maximum time is ~2150 UTC and minimum time is ~1970 UTC.

Time may be delayed by up to 10 ms due to FSW polling delay. Maximum time is ~2150 UTC and minimum time is ~1970 UTC.
- Milliseconds since 1970-01-01 00:00:00 UTC at end of reading. [ICON_L27_Time_UTC_Stop]
Milliseconds since 1970-01-01 00:00:00 UTC at end of reading. Time is generated from the time-code at byte 1015 of the IVM packet minus the time sync at byte 1019 of the IVM packet. This is the GPS time at the start of the integration period. The integration period is assumed to be 4 seconds so the center time is 2 seconds after that. The formula is (time-code * 1000ms) + 2000ms - (16 * time sync / 1000) in GPS milliseconds then converted to UTC time. See the UTD 206-024 Rev A document.

References: 1.Troshichev O.A. et al, Planet.Space Sci., 36, 1095, 1988. 2.Vennerstrom S. et al, Report UAG-103, World Data Center A for STP, Boulder, April 1994 PC-index is an empirical magnetic activity index based on data from single near-pole station (Thule or Vostok for N or S hemispheres, respectively). Its derivation procedure is optimized to achieve the best correlation of PC-index with the solar wind electric field (SWEF) magnitude ( v*B*sin(teta/2)**2 ). The averaged horizontal magnetic disturbance vector (quiet value subtracted) is projected onto the optimal direction (defined empirically for each UT hour and each season based on the best correlation with the SWEF) and, after normalization to the equivalent value of SWEF, it gives the PC-index (expressed in mV/m). Although PC-index is formally expressed in mV/m, it actually represents the measure of magnetic activity, the normalization procedure (to SWEF) helps to reduce the seasonal/diurnal effects to facilitate the intercomparison. The resolution of the northern cap PC-index is 5 min and of the one from southern cap - 15 min. However, one time scale with the 5 min step is used for both indices and each 15 min averaged value of southern index is, hence, repeated for three times.

- IM_ELECTRON_DENSITY_RPI (spase://NASA/NumericalData/IMAGE/RPI/PT1M)
- Description
The electron density values listed in this file are derived from the IMAGE Radio Plasma Imager (B.W. Reinisch, PI) data using an automatic fitting program written by Phillip Webb with manual correction. The electron number densities were produced using an automated procedure (with manual correction when necessary) which attempted to self-consistently fit an enhancement in the IMAGE RPI Dynamic Spectra to either 1) the Upper Hybrid Resonance band, 2) the Z-mode or 3) the continuum edge. The automatic algorithm works by rules determined by comparison of the active and passive RPI data [Benson et al., GRL, vol. 31, L20803, doi:10.1029/2004GL020847, 2004]. The manual data points are not from frequencies chosen freely by a human. Rather the human specifies that the computer should search for a peak or continuum edge in a certain frequency region. Thus even the manual points are determined, in part, by the automatic algorithms. Of course that does not guarantee that the data points are right, but it does eliminate some human bias. For a more detailed description see .http://ulcar.uml.edu/rpi.html.

- ISEE-3_MAG_1MIN_MAGNETIC_FIELD (spase://NASA/NumericalData/ISEE3/MAG/CDF/PT1M)
- Description
This data set contains averaged 1-minute magnetic field data converted from simple ASCII records. It was created at NSSDC from a more complex, multi-resolution data set (NSSDC ID = SPHE-00673; Old ID = 78-079A-02D) provided by the Principal Investigator team and now available from https://spdf.gsfc.nasa.gov/pub/data/isee/isee3/magnetic_fields/ The coordinate system for the B-field components is the JPL-defined I,S coordinate system (origin at the spacecraft): I is the unit vector in the direction of the ISEE-3 spin axis (positive in the northward direction), and S is the unit vector from the spacecraft to the sun. The z-axis is parallel to to I, the y-axis to the cross-product I x S, and the x-axis to Y x Z. The I,S coordinate system is approximately the same as the Solar Ecliptic (SE) system since the spacecraft z-axis (the spin axis) is maintained within 0.5 degree of perpendicular to the ecliptic plane. (SE is defined the same way as GSE, but with the spacecraft [point of observation] substituted for Earth). For years 1984-1990 we added spacecraft position in HGI coordinate The HGI coordinates are Sun-centered and inertially fixed with respect to an X-axis directed along the intersection line of theecliptic and solar equatorial planes, and defines zero of the longitude, HGI_LONG. The solar equator plane is inclined at 7.25degrees from the ecliptic. This direction was towards ecliptic longitude of 74.367 deg on 1 January 1900 at 12:00 UT; because of the precession of the Earth"s equator, this longitude increases by 1.4 deg/century. The Z-axis is directed perpendicular to and northward of the solar equator, and the Y-axis completes the right-handed set. The longitude, HGI_LONG increase from zero in the X-direction towards Y-direction.The latitude HG_LAT increases to +90 deg towards the north pole, and to -90 deg towardsm south pole. Note that here present values averaged in 1-minute, e.g. <B>^2 may be not equal <B^2)>.

- Description
Data coverage includes the region from 6 earth radii out to (but excluding) the bow shock. The reasons for selecting this area of coverage are that the solar wind ion distributions are too cold to be adequately resolved by this instrument, and inside the region of 6 earth radii the fast plasma data would be contaminated by the energetic particle background. The data are provided at a temporal resolution of approximately 60 seconds. They represent moments of individual two-dimensional (2D) distributions obtained in approximately 3 or approximately 6 seconds (see below). No time averaging over longer intervals is involved; instead, the temporal resolution of the full data set (approximately 3 / 6 / 12 s) was reduced to approximately 60 s. The UT given indicates the start of the respective sampling interval. For a description of the instrument see Bame et al., 1978 (IEEE Transact. Geosci. Electron. GE-16, 216) and Bame et al., 1993 (Rev. Sci. Inst., 64, 1026). Remarks about the computation of the moments may be found in Paschmann et al., 1978 (Space Sci. Rev. 22, 717). The moments were computed for three 'species', but only the ion moments are included here: lop (low-ener. ions, ~1eV/e-~130eV/e); hip (hi-ener. ions, ~130eV/e-~45keV/e); alle (electrons, ~30eV - ~45keV). The moments are computed after the fluxes are corrected for background and s/c potential. Algorithms for these corrections are relatively unsophisticated, so the moments are suspect during times of high background and/or high spacecraft potential. Because the determined spacecraft potential is not very precise, the magnitude of the low-energy ion flow velocity is probably not accurate, but the flow direction is well determined. Tperp and Tpara are obtained from diagonalization of the 3-dimensional temperature matrix, with the parallel direction assigned to the eigenvalue which is most different from the other two. The corresponding eigenvector is the symmetry axis of the distribution and should be equivalent to the magnetic field direction. The eigenvalue ratio Tperp/Tmid, which is provided for each species, is a measure of the symmetry of the distribution and should be ~1.0 for a good determination. Several of the parameters have a fairly high daily dynamic range and for survey purposes are best displayed logarithmically. These parameters are indicated by a 'SCALETYP' value of 'linear' in this file. A quality Flag value of 1 indicates that the values are suspect because of unreliable location info.

- Description
These data are high temporal resolution solar wind ion moments derived from measurements obtained by the Los Alamos X-Fan Solar Wind Ion Experiment (SWE) on ISEE-1. The data cover the solar wind seasons for the spacecraft (roughly July through December) from 1977 through 1983. The temporal resolution is 24 seconds at high data rate and 48 seconds at low data rate. Among the parameters, the flow azimuth is given in degrees, with 0 degrees corresponding to flow from the sun [corrected for aberration] and positive azimuths corresponding to flow toward dawn; flow latitude is in degrees, with positive latitudes corresponding to flow toward the south; an alpha/proton fraction of 0.00 means no determination was made. The data providers did not attempt to cross-calibrate density values with those from other experiments. However, they expected that density values will tend to be too low in later years because of detector degradation. Cross-calibration using, for example, IMP-derived values would be a useful exercise. Please note also that many of these measurements were obtained within the foreshock region where the solar wind flow is affected by waves in the foreshock. References: Los Alamos Magnetospheric Plasma Analyzer (MPA) [Bame et al., ISEE-1 and ISEE-2 fast plasma experiment and the ISEE-1 solar wind experiment, IEEE Trans. Geosci. Electron., GE-16, 216, 1978]; Los Alamos Magnetospheric Plasma Analyzer (MPA) [Bame et al., Magnetospheric plasma analyzer for spacecraft with constrained resources, Rev. Sci. Instrum., 64, 1026 (1993)]. The moments are presented in s/c coordinates: the z-axis is aligned with the spin axis, which points radially toward the center of the Earth; the x-axis is in the plane containing the spacecraft spin axis and the spin axis of the Earth, with +X generally northward; and the y-axis points generally eastward. Polar angles are measured relative to the spin axis (+Z), and azimuthal angles are measured around the z-axis, with zero along the +X direction. The moments are computed after the fluxes are corrected for background and s/c potential. Algorithms for these corrections are relatively unsophisticated, so the moments are suspect during times of high background and/or high spacecraft potential. Because the determined spacecraft potential is not very precise, the magnitude of the low-energy ion flow velocity is probably not accurate, but the flow direction is well determined.

- Data Variable Descriptions
- Spin Plane E-Field Spectra, 215 meter long-wire antenna [Ev_Spectra]
These data are collected via the fine wire electric dipole antenna which had a tip to tip length of 215 meters. The Ev antenna was used to collect over 99% of the E-field measurements obtained by the PWI. Most of the time (98.3%) these data were collected via the ESA (Electric Spectrum Analyzer). Though a small fraction of the data are from the MSA (Magnetic Spectrum Analyzer). The two analyzers have almost identical channel centers and bandwidths, except that ESA has 6 more bands above the highest band of the MSA. When the MSA is used to read an electric antenna, the upper 6 bands are marked with fill data. This antenna was shared with the Heppner DC electric-field experiment. The 'E_Quality' variable flags times when known spacecraft noise sources are present in the E-field data.
- Spin Plane E-Field Spectra, 73.5 meter two-sphere antenna [Eu_Spectra]
Less that 0.5% of electric spectra in this data set were collected via the Eu antenna. This variable is almost always <b>empty</b>. The Eu sensor is a two-sphere electric antenna which had a sphere-to-sphere separation of 73.5 meters. The spheres on the u-axis have a diameter of 8.0 cm and each contains a high-impedance preamplifier which provides signals to the main electronics box which contained the spectrum analyzers. This antenna was shared with the Mozer quasi-static electric-field instrument. Consult the 'E_Quality' variable for issues regarding Ev_Spectra values.
- Spin Axis B-Field Spectra, Bz search coil [Bz_Spectra]
These data are collected via the z-axis Magnetic Search Coil (Bz) which has an upper cutoff frequency of 10 kHz. It's constructed of a 16 inch mu-metal core and wound with 10000 turns wire. Almost 99% of all magnetic field measurements from the PWI were collected via the Bz search coil. NOTE: When they are present at all, the upper 6 frequency indices contain data collected above the search coil's upper cutoff frequency. Though these data are included for completeness, all samples above 10 kHz are *not* calibrated data and should be used with caution. See the 'B_Quality' variable and the 'Quality_note' for issues regarding Bz_Spectra
- Spin Plane B-Field Spectra, Bv search coil [Bv_Spectra]
These data were collected via the V-axis Magnetic Search Coil (Bv). This coil had the same physical properties as the Bz coil but was mounted perpendicular to the Bz coil. The Bv coil axis pointed along the V direction, which is within the spacecraft spin plane. This variable is usually *empty*. Less than 2.5% of magnetic spectra were collected via this search coil. See the 'B_Quality' variable and the 'Quality_note' for issues regarding Bu_Spectra.
- Spin Plane B-Field Spectra, Bu search coil [Bu_Spectra]
These data were collected via the U-axis Magnetic Search Coil (Bu). This coil had the same physical properties as the Bv coil but was mounted perpendicular to both the Bz and Bv coils. The Bu coil axis pointed along the U direction, which is also within the spacecraft spin plane. This variable is almost always *empty*. Less than 0.1% of magnetic spectra were collected via this search coil. See the 'B_Quality' variable and the 'Quality_note' for issues regarding Bu_Spectra.

- Description
Data coverage includes the region from 6 earth radii out to (but excluding) the bow shock. The reasons for selecting this area of coverage are that the solar wind ion distributions are too cold to be adequately resolved by this instrument, and inside the region of 6 earth radii the fast plasma data would be contaminated by the energetic particle background. The data are provided at a temporal resolution of approximately 60 seconds. They represent moments of individual two-dimensional (2D) distributions obtained in approximately 3 or approximately 6 seconds (see below). No time averaging over longer intervals is involved; instead, the temporal resolution of the full data set (approximately 3 / 6 / 12 s) was reduced to approximately 60 s. The UT given indicates the start of the respective sampling interval. For a description of the instrument see Bame et al., 1978 (IEEE Transact. Geosci. Electron. GE-16, 216) and Bame et al., 1993 (Rev. Sci. Inst., 64, 1026). Remarks about the computation of the moments may be found in Paschmann et al., 1978 (Space Sci. Rev. 22, 717). The moments were computed for three 'species', but only the ion moments are included here: lop (low-ener. ions, ~1eV/e-~130eV/e); hip (hi-ener. ions, ~130eV/e-~45keV/e); alle (electrons, ~30eV - ~45keV). The moments are computed after the fluxes are corrected for background and s/c potential. Algorithms for these corrections are relatively unsophisticated, so the moments are suspect during times of high background and/or high spacecraft potential. Because the determined spacecraft potential is not very precise, the magnitude of the low-energy ion flow velocity is probably not accurate, but the flow direction is well determined. Tperp and Tpara are obtained from diagonalization of the 3-dimensional temperature matrix, with the parallel direction assigned to the eigenvalue which is most different from the other two. The corresponding eigenvector is the symmetry axis of the distribution and should be equivalent to the magnetic field direction. The eigenvalue ratio Tperp/Tmid, which is provided for each species, is a measure of the symmetry of the distribution and should be ~1.0 for a good determination. Several of the parameters have a fairly high daily dynamic range and for survey purposes are best displayed logarithmically. These parameters are indicated by a 'SCALETYP' value of 'log' in this file. A quality Flag value of 1 indicates that the values are suspect because of unreliable location info.

- IT_H0_MFI (spase://NASA/NumericalData/Interball-1/MIFM/PT6S)
- Description
Magnetic field measurements on the Interball- Tail satellites are carried out by IZMIRAN and Space Research Institute RAS (SRI) since 1995. Satellite has the orbits with apogee 200000 (30 Re) and perigee 500 km. and provides measurements in the solar wind and in the different regions of the magnetosphere at the same time with Geotail, Polar and Interbal-A working in the magnetosphere and Wind, ACE in the solar wind. Magnetic field measurements on-board the Interball Tail Probe are carried out by the FM-3I and MFI instruments. FM-3I consists of two flux-gate magnetometers M1 and M2 covering two different ranges: 200 nT and 1000 nT. The M2 instrument is mostly used to perform the attitude control of the INTERBALL TAIL spacecraft. M1 magnetometer data are transmitted to the scientific SSNI telemetry system at rates 0.125-16 vectors/s depending on the instrument operating mode. The magnetic field data from the M2 magnetometer are transmitted at the rate 1 vectors per 6 sec. to the BNS attitude control system. MFI magnetometer has the next parameters: measured range 0.3-37.5 nT, frequency range 0-2 Hz, sampling rate from 1/4 to 8 measurements per second. FM-3 M2 magnetometer failed in February 1996, FM-3 M1 and MFI are working until now. Data presented here are the combination of the data of all magnetometers. First of all FM-3 M1 data are used, if they are absent, used MFI data and if data of both magnetometer are absent, FM-3 M2 data presented. In case of FM-3 M1 and MFI, data are averaged for 6 seconds intervals. - Modification History
