Description

This CDAWeb-accessible data set contains 30-minute, spin-averaged count rates and fluxes, and their statistical uncertainties, of energetic particles from the IMP8 GME experiment. Included are fluxes of: protons in 30 energy bins from 0.88-1.15 to 327-485 MeV; alpha particles in 21 energy bins from 1.14-1.36 to 63.3-81.0 MeV/n; and 0.3-18 MeV electrons. Also included are count rates for each of 7 sensors and for 11 multi-sensor coincidence modes. Proton and alpha particle fluxes, for every other energy bin, are given at the FTPBrowser and MSSP interfaces identified below.
