Description

This data set contains coincidence mode counts and
accumulation times, plus "box counts" based on pulse height analysis (PHA),
at 15-min resolution. There are 11 coincidence mode counts and 27 "box
counts." Taken together, the parameters included allow computation of
average counting rates and of fluxes of protons, electrons, helium and
CNO nuclei in selected energy windows corresponding to the PHA boxes.
There are 12 proton boxes spanning 3-67 MeV, 5 helium boxes spanning
3-67 MeV/n, 5 electron boxes, 2 Z>2 boxes, 1 box each for CNO, Z>5, and
E>67 MeV/n.
