            <Description>Each table (CSV file) captures the numbers 
of counts of arriving energetic neutral atoms, as integrated 
over a full 8-day orbit, for a single IBEX-Lo energy step, 
for one of two categories of species (hydrogen, oxygen plus
carbon, the latter being labelled "Oxygen" in file names).  
Numbers of counts are given in 360 1-degree bands in
spacecraft spin phase.  Each table is CSV-formatted Excel.  
Each subdirectory is for a given energy band and has the 
tables (files) for each of several orbits for each of the two 
species categories.</Description>

				Release_2 contained only IBEX-Hi map data.  Extensions to later times for this data set may be forthcoming in the future.</Note>
