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
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.
