CRRES HEEF electron equatorial distributions vs.L
This data set holds half-orbit (~5 hour) resolution \nelectron distributions (19 5-deg equatorial pitch angles vs. 19 energies) \nfrom the High Energy Electron Fluxmeter (HEEF) on the CRRES spacecraft. \nThe energy range covered is 0.3-7.5 MeV. These data are developed from \nthe 1-min insitu pitch angle distributions by assigning each 5-deg bin \nin pitch angle a corresponding McIlwain L value and then by mapping the \ninsitu pitch angle distribution to the equator, into 0.05-wide L bins, \nassuming first adiabatic invariant conservation. The mapping yields \nequivalent equatorial pitch angles. Flux data are for a given half-orbit, \ngiven 0.05-wide L bin, given equatorial pitch angle and given energy bin\nare then averaged. Data records are for a given half-orbit and given\nL bin; each record contains averaged fluxes vs. equatorial pitch angle\nand energy. The data are in SGI(UNIX) binary format. Read software\nis contained within the companion documentation.
