I1_AV2_OTT (spase://NASA/NumericalData/ISIS1/SFS/AverageIonogram/Version2/Ottawa/PT29S)

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. More information can be found

I1_AV_KER (spase://NASA/NumericalData/ISIS1/SFS/AverageIonogram/KerguelenIsland/PT29S)

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 692). 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. More information can be found

I1_NEPROF_TOPS (spase://NASA/NumericalData/ISIS1/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.

I2_AV_ADL (spase://NASA/NumericalData/ISIS2/SFS/AverageIonogram/TerreAdelie/PT22S)

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.

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.

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.

IBEX_H3_ENA_HI_R02_CG_NOSP_OMNI_6MO (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R02/CG/noSP/Omni/6mo)

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.

IBEX_H3_ENA_HI_R02_NOCG_NOSP_OMNI_6MO (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R02/noCG/noSP/Omni/6mo)

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.

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 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

8: This particular data set, denoted in the original ascii files as
hvset_cg_mapX for N=1-6, in which N indicates a map number, includes pixel map
data from all directions (omnidirectional), 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 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.

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.

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.

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.

IBEX_H3_ENA_HI_R04_CG_SP_RAM_1YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/CG/SP/RAM/1yr)

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. The following list associates Release 16 map numbers (1-22) with mission year

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_HI_R04_DEFLECTION_1AU_7DAY (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/DEFL/1AU/7dy)

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

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.

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_HI_R04_LOSS_1AU_7DAY (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/LOSS/1AU/7dy)

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.loss1au , 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

IBEX_H3_ENA_HI_R04_NOCG_NOSP_ANTIRAM_1YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/NOCG/NOSP/ANTIRAM/1yr)

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

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.

IBEX_H3_ENA_HI_R04_NOCG_NOSP_OMNI_3YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/NOCG/NOSP/OMNI/3yr)

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.

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 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

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

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. The following list associates Release 16 map numbers (1-22) with mission year

8: This particular data set, denoted in the original ascii files as
hvset_tabular_mapN for N=1 - 6, which indicates a map number, includes pixel map
data from all directions (omnidirectional), no CG, 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 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. The following list associates Release 16 map numbers (1-22) with mission year

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.

IBEX_H3_ENA_HI_R04_SURVPRO_1AU_7DAY (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R04/SurvPro/1AU/7dy)

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

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.

IBEX_H3_ENA_HI_R07_CG_NOSP_ANTIRAM_MIF_5YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/CG/noSP/ANTIRAM/MIF/5yr)

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

IBEX_H3_ENA_HI_R07_CG_NOSP_ANTIRAM_VEIF_5YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/CG/noSP/ANTIRAM/VEIF/5yr)

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 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

hvset_noSP_antiram_cg_year_1to5combinedVarEnergyInertialFrame are pixel map data
antiram-directional in Var Energy Inertial Frame, CG, no SP, 5 year cadence. 

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
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.

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

8: This particular data set, denoted in the original ascii files as
hvset_cg_map_1to10combinedMonoInertialFrame are pixel map data from all
directions (omnidirectional) in Mono Inertial Frame, CG, no SP, 5 year cadence. 

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.

IBEX_H3_ENA_HI_R07_CG_NOSP_OMNI_VEIF_10MP (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/CG/noSP/Omni/MIF/5yr)

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 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

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.

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
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 SCF Frame

hvset_noSP_ram_cg_year_1to5combinedMonoInertialFrame are pixel map data
ram-directional in Mono Inertial Frame, CG, no SP, 5 year cadence. 

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.

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:

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

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.

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

8: This particular data set, denoted in the original ascii files as
hvset_tabular_antiram_cg_year_1to5combinedMonoInertialFrame are pixel map data
antiram-directional in Mono Inertial Frame, CG, SP, 5 year cadence. 

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.

IBEX_H3_ENA_HI_R07_CG_SP_ANTIRAM_VEIF_5YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/CG/SP/ANTIRAM/VEIF/5yr)

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 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

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.

8: This particular data set, denoted in the original ascii files as
hvset_cg_tabular_mapX, where X = 1-10 are pixel map data from all directions
(omnidirectional), CG, 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.

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

hvset_cg_tabular_map_1to10combinedMonoInertialFrame are pixel map data from all
directions (omnidirectional) in Mono Inertial Frame, CG, no SP, 5 year cadence. 

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-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 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:

5: http://doi.org/10.3847/1538-4365/aa66d8  
6. The following codes are used to define dataset types:

In the original data this mode is denoted as Tabular. 
noSP - no survival probability corrections have been applied to the data.

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.

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

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
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

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:

hvset_noSP_antiram_yearN for N=1,5, includes pixel map data from antiram

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

8: This particular data set, denoted in the original ascii files as
hvset_noSP_antiram_year_1to5combinedVarEnergySCFrame are pixel map data
antiram-directional in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

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 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

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.

IBEX_H3_ENA_HI_R07_NOCG_NOSP_OMNI_VESCF_10MP (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/noCG/noSP/Omni/VESCF/5yr)

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. 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

8: This particular data set, denoted in the original ascii files as
hvset_map_1to10combinedVarEnergySCFrame are pixel map data from all directions
(omnidirectional) in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

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.

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

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

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

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

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
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.

8: This particular data set, denoted in the original ascii files as
hvset_SP_antiram_nocg_yearN for N=1,5, includes pixel map data from antiram
direction (antiram-directional), no 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.

IBEX_H3_ENA_HI_R07_NOCG_SP_ANTIRAM_VESCF_5YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/NOCG/noSP/ANTIRAM/VESCIF/5yr)

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. 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

hvset_noSP_antiram_year_1to5combinedVarEnergySCFrame are pixel map data
antiram-directional in Var Energy SC Frame, no CG, no SP, 5 year cadence. 

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 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

8: This particular data set, denoted in the original ascii files as
hvset_tabular_map_1to10combinedVarEnergySCFrame are pixel map data from all
directions (omnidirectional) in Var Energy SC Frame, no CG, SP, 5 year cadence. 

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.

IBEX_H3_ENA_HI_R07_NOCG_SP_RAM_1YR (spase://VSPO/NumericalData/IBEX/H3/ENA/Hi/R07/NOCG/SP/RAM/1yr)

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
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.

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.
