IBEX High Energy Neutral Atom Imager (Hi) Data Release 18, Compton-Getting corrected, not Survival Probability corrected, Ram-directional, West Ecliptic ENA Maps, Level H3, one-year average Data

IBEX-Hi Release 18 one-year average Solar Ecliptic hydrogen ENA maps from ram-direction observations. Compton-Getting correction has been applied to the flux spectra to account for spacecraft motion relative to the arriving ENAs. Survival-probability correction has not been applied; the fluxes have not been scaled from the IBEX observing location near 1 AU to approximately 100 AU by that correction. The source metadata describes observations for 2009-2022, with measurement intervals spanning 2008-12-25 through 2022-12-26. The maps contain 60 longitude bins by 30 latitude bins at six-degree spacing for IBEX-Hi energy channels 2-6. The channel 2-6 nominal energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV, and the corresponding instrument FWHM 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 parameters include mapped energy, differential flux, signal-to-noise ratio, flux variance, total counts, exposure time, samples per pixel, and CDAWeb X/Y alternate views, together with Flux*_movie views for time-sequenced rendering. The source ASCII filename pattern is hvset_noSP_ram_cg_N/hv60.hide-trp-flux100-hi-R-F.txt. The CDAWeb ProductKey is IBEX_H3_ENA_HI_R18_CG_NOSP_RAM_1YR.
