Description

IBEX-Hi Release 8 five-year globally distributed flux (GDF) component maps derived from the Ribbon/GDF separation 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 ecliptic longitude and latitude 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 CDAWeb ProductKey is IBEX_H3_ENA_HI_R08_OMNI_F3-GDF-MAPS-J2000_5YR.

Caveats
This is a derived globally distributed flux (GDF) component map product from IBEX Release 8, produced by separating the Ribbon from the globally distributed ENA emission. The ProductKey does not state a Compton-Getting or survival-probability processing state. IBEX documentation describes its sky maps in J2000 ecliptic coordinates, while CDAWeb describes this exact ProductKey as a five-year-average West Ecliptic map and the upstream CDF support-variable labels retain Solar Ecliptic terminology. The SPASE display names therefore follow the J2000 ecliptic product identity while preserving the CDF ParameterKey values. SPASE 2.7.1 J2000 denotes the equatorial J2000 celestial frame, so no CoordinateSystem element is assigned here for the J2000 ecliptic map frame.
