There are 11 coincidence mode counts and 27 \"box \ncounts.\"  Taken together, the parameters included allow computation of \naverage counting rates and of fluxes of protons, electrons, helium and \nCNO nuclei in selected energy windows corresponding to the PHA boxes.\nThere are 12 proton boxes spanning 3-67 MeV, 5 helium boxes spanning\n3-67 MeV/n, 5 electron boxes, 2 Z>2 boxes, 1 box each for CNO, Z>5, and \nE>67 MeV/n.",
