            <Description>Hydrogen ENA fluxes in each of three IBEX-Lo energy 
bands in each of 21,600 [720(longitude) by 30(latitude)] bins, 
accumulated over 6 months.  Bins are defined in J2000 ecliptic 
coordinates.  Maps are available for energy bands 5 (209 eV), 
6 (439 eV), and 7 (872 eV).  Digital image files are between 290 and 
310 KB in size.  Images in PNG format are identified by VEPO as a 
separate data product.</Description>

                <Note>Data are planned for 6-month releases.  However,
				Release_2 contained only IBEX-Hi map data.  Extensions to later times for this data set may be forthcoming in the future.</Note>

                <Description>The array has 720 rows and 30 columns.  
Row 1 (30) is for the north (south) ecliptic polar region.  The 
columns start at zero ecliptic longitude and step through to 
ecliptic longitude 360.  The first and last columns have the 
same values.</Description>
