Added PublicationInfo and DOI. tlk IBEX-Hi Release 8 five-year Ribbon-component maps derived by separating Ribbon energetic neutral atom emissions from the globally distributed flux using the first five years of IBEX observations (2009-2013). This CDF contains omnidirectional differential hydrogen ENA flux maps for IBEX-Hi energy channels 2-6 on a 60 by 30 J2000 right ascension and declination grid. Channel 2-6 FWHM energy ranges are 0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, and 3.13-6.00 keV; the corresponding nominal energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV.

The five-year time span corresponds to IBEX mission years 1 through 5, from 2008-12-25 through 2013-12-26. The DOI listed in InformationURL is for the associated publication, not a dataset DOI. The ProductKey and provider documentation identify this as a J2000 ecliptic map product, but copied CDF support-variable FIELDNAM and CATDESC attributes still say Solar Ecliptic. The SPASE parameter names and descriptions follow the J2000 ecliptic product identity while preserving the upstream CDF ParameterKey values.
