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.
