As of this writing (11/5/2010), this product had been issued by the IBEX team in two releases. Release 1 IBEX-Hi map data are superseded by Release 2 data which are more time-extensive (12 months vs. 6 months) and are richer in content. While Release 1 IBEX-Hi map data and their documentation remain accessible at ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/ibex/hi/maps/digital_data/release_1/ and ftp://nssdcftp.gsfc.nasa.gov/spacecraft_data/ibex/hi/maps/images/release_1/, this description supports the retrieval and use of Release 2 data only. The Release_2 IBEX-Hi map data contain all-sky 6 deg x 6 deg resolution maps in J2000 ecliptic coordinates of energetic neutral fluxes reaching the near-Earth IBEX spacecraft from the distant heliosphere and heliosheath. Maps are in both a spacecraft frame and, via Compton-Getting corrections, a heliospheric frame. Basic maps are each accumulated over 6-months duration, so far for epochs 1 (12/2008-06/2009) and 2 (06/2009-12/2009). Maps are available for five of the energy bands of IBEX-Hi (0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV) and, for the heliospheric frame only, also for six monoenergetic points (0.71, 1.11, 1.74, 2.73, 3.0, 4.29 keV). In addition, monoenergetic maps are available as summed over the data collected during epochs 1 and 2 combined. All maps are available in digital text format and in PNG image format (considered as separate data sets within VEPO). Given that VHO/VEPO typically displays clickable granule (file) names for any given specification of data product and time span, and given that IBEX-Hi digital maps and PNG-formatted display maps are each considered single data products, a request for data from either product will yield .GE.20 names of files containing data spanning or within the requested time span. For IBEX, the names shown by VHO/VEPO actually have the form subdirectory/filename. The subdirectories are named map1, map1cg, map2, map2cg, and map-combined. Maps involving "1" ("2") are from the first (second) 6-month epoch, while "combined" means composed of data taken during epochs 1 and 2. Maps involving (not involving) "cg" means heliospheric frame (spacecraft frame). In the first four subdirectories, file names are of the forms ha60.hide-trp-flux100-hi-N-flux.ext and ha60.hide-trp-mono_80-P.PP-flux.ext, where "ext" is "png" or "txt" according to which product is requested, N is the energy step number for the IBEX-Hi instrument (2-6), P.PP is the energy level, in keV, of a monoenergetic flux. Files in the "combined" subdirectories are named "combined-P.PP-flux.ext, where P.PP has the same meaning as above. In addition to the flux maps to which VEPO provides access, several map files whose data support the determination of the fluxes are also available in the underlying nssdcftp directories and are described by aareadme files there (and by IBEX web pages at SWRI: http://ibex.swri.edu/ibexpublicdata/Data_Release_2/)
