Included is a\ntime tag (seconds since 00:00 UT of January 6, 1980), an arrival\ndirection (R.A. and Dec. in J2000 celestial coordinates), the IBEX\nlocation, ENA energy band, species (hydrogen or oxygen) and \ncoincidence type.  Data files are given for each 8-day orbit and \nfor each of the 8 IBEX-Lo energy bands.  The data files are in \nASCII.","Acknowledgement":"The IBEX Team","PublicationInfo":{"Authors":"McComas, David J.","PublicationDate":"2025-11-14T16:02:23Z","PublishedBy":"Space Physics Data Facility"},"Contact":{"PersonID":"spase://SMWG/Person/David.J.McComas","Role":"PrincipalInvestigator"},"InformationURL":[{"Name":"Readme file at SPDF","URL":"https://spdf.gsfc.nasa.gov/pub/data/ibex/release3/lo/time_series/TS_description.txt","Description":"This file was created by the IBEX team."},{"Name":"HelioData","URL":"https://helio.data.nasa.gov/dataset/IBEX_Lo_Direct_Events","Description":"The HelioData dataset page provides an overview of the dataset with access links, associated variables, and more."}],"PriorID":["spase://VEPO/NumericalData/IBEX/Lo/Direct_Events","spase://VSPO/NumericalData/IBEX/Lo/Direct_Events"]},"AccessInformation":{"RepositoryID":"spase://SMWG/Repository/NASA/GSFC/SPDF","Availability":"Online","AccessRights":"Open","RightsList":{"Rights":{"SchemeURI":"https://spdx.org/licenses/","RightsIdentifierScheme":"SPDX","RightsIdentifier":"CC0-1.0","RightsURI":"https://spdx.org/licenses/CC0-1.0.html","RightsName":"Creative Commons Zero v1.0 Universal","Note":"CC0 1.0 Universal is the Creative Commons license applicable to all publicly available NASA Heliophysics data products"}},"AccessURL":[{"Name":"FTPS from SPDF (not with most browsers)","URL":"ftps://spdf.gsfc.nasa.gov/pub/data/ibex/release3/lo/time_series/direct_events/","Description":"Directory with energy-range-specific subdirectories"},{"Name":"HTTPS from SPDF","URL":"https://spdf.gsfc.nasa.gov/pub/data/ibex/release3/lo/time_series/direct_events/","Description":"In CDF via HTTP from SPDF"}],"Format":"Text","DataExtent":{"Quantity":"700","Units":"MB","Per":"P1Y"},"Acknowledgement":"The IBEX Team"},"InstrumentID":"spase://SMWG/Instrument/IBEX/Lo","MeasurementType":"NeutralAtomImages","TemporalDescription":{"TimeSpan":{"StartDate":"2008-12-25T00:00:00Z","StopDate":"2009-06-19T00:00:00Z","Note":"Data are planned for 6-month releases.
