Description

IBEX-Hi Release 15 three-year Ribbon-centered hydrogen ENA maps with Compton-Getting and survival-probability corrections applied. The three-year average combines mission years 2009, 2010, and 2011. The science arrays are 60 by 30 Solar West Ecliptic longitude and latitude 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 corresponding nominal energies are 0.71, 1.11, 1.74, 2.73, and 4.29 keV. Flux-variance arrays (Fvar2-Fvar6) are also included. The CDAWeb ProductKey is IBEX_H3_ENA_HI_R15_CG_SP_RIBCEN_3YR.

Caveats
RIBCEN denotes Ribbon-centered processing/reference geometry. The CDF coordinate support variables themselves are Solar Ecliptic latitude and east/west longitude, so the SPASE CoordinateSystem for map axes is SE. The CDF source metadata gives the energy-dependent Ribbon centers in ecliptic J2000 longitude/latitude as ESA2 [218.5,43.1], ESA3 [220.3,40.5], ESA4 [219.6,39.8], ESA5 [217.9,37.7], and ESA6 [214.2,32.4] degrees. These center values describe the Ribbon-centered construction and are not separate CDF coordinate variables.
