            <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 three categories of species (hydrogen, oxygen plus
carbon, and hydrogen plus oxygen plus carbon, the latter 
two being labelled "Oxygen" and "All," respectively in file
names).  Numbers of counts are given in 1024 0.33-nanosecond 
TOF bins ranging from 0-0.33 ns to 339.67-340 ns.  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 three 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>
