IBEX High Energy Neutral Atom Imager (Hi) Data Release 18, no Compton-Getting correction, Survival Probability corrected, Ram-directional, Equatorial ENA Maps, Level H3, fourteen-year average Data

IBEX-Hi Release 18 fourteen-year combined Equatorial hydrogen ENA maps from ram-direction observations. The flux spectra have not been Compton-Getting corrected for spacecraft motion. Survival-probability correction has been applied to account for ENA ionization losses during propagation, including photoionization and charge exchange with solar-wind protons, and to scale fluxes from the IBEX observing location near 1 AU to approximately 100 AU. The product spans 2008-12-25 through 2022-12-26 and contains 60 by 30 all-sky maps 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 CDF variables described by this record include mapped energy, differential flux, signal-to-noise ratio, flux variance, counts, exposure time, samples per pixel, and virtual CDAWeb alternate views. The CDAWeb ProductKey is IBEX_H3_ENA_HI_R18_NOCG_SP_RAM_EQUA_14YR.
