CRRES PROTEL proton equatorial distributions vs.L

ResourceID
spase://NASA/NumericalData/CRRES/PROTEL/PT5H

Description

This data set holds half-orbit (~5 hour) resolution
proton distributions (19 5-deg equatorial pitch angles vs. 24 energies)
from the Proton Telescope (PROTEL) on the CRRES spacecraft.
The energy range covered is 1-100 MeV. These data are developed from
the 1-min insitu pitch angle distributions by assigning each 5-deg bin
in pitch angle a corresponding McIlwain L value and then by mapping the
insitu pitch angle distribution to the equator, into 0.05-wide L bins,
assuming first adiabatic invariant conservation. The mapping yields
equivalent equatorial pitch angles. Flux data for a given half-orbit,
given 0.05-wide L bin, given equatorial pitch angle and given energy bin
are then averaged. Data records are for a given half-orbit and given
L bin; each record contains averaged fluxes vs. equatorial pitch angle
and energy. The data are in SGI(UNIX) binary format. Read software
is contained within the companion documentation.
