ZCB This data set holds 1-min resolution electron distributions (19 5-deg pitch angles vs. 19 energies) from the High Energy Electron Fluxmeter (HEEF) on the CRRES spacecraft. The energy range covered is 0.3-7.5 MeV. The data are in SGI(UNIX) binary format. Read software is contained within the companion documentation. Please acknowledge Donald Brautigam at AFRL.
