Pioneer 11 Charged Particle Composition(CPC) 15-min Count Rates

Published by SPDF | National Aeronautics and Space Administration | Catalog Last Checked: September 09, 2026 at 12:36 AM | Dataset Last Updated: September 07, 2026
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.
