IBEX High Energy Neutral Atom Imager (Hi) Data Release 18, No Compton-Getting correction, Survival Probability corrected, ANTIRAM Upper Ribbon separated ENA Maps, Level H3, one-year Data

IBEX-Hi Release 18 one-year ANTIRAM hydrogen ENA maps for the upper Ribbon separated-map product from the Release 18 Ribbon/GDF separation. No Compton-Getting correction has been applied; survival-probability correction has been applied to account for ENA losses during transport and to scale fluxes from the IBEX observing location near 1 AU to approximately 100 AU. The data cover 2009 through 2022, with measurement intervals spanning 2008-12-25 through 2022-12-26, on a 60 by 30 Solar Ecliptic longitude-latitude grid for IBEX-Hi energy channels 2-6. The 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 nominal energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. The source metadata identifies this as the upper Ribbon separated-map variant. Variables include differential flux, flux variance, total exposure time, and virtual CDAWeb alternate-view variables. The CDAWeb ProductKey is IBEX_H3_ENA_HI_R18_NOCG_SP_ANTIRAM_UPPER_RIBBON_1YR.
