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 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.
