IMP 8 Cosmic Ray Nuclear Composition (CRNC) hourly energetic electron fluxes

ResourceID
spase://NASA/NumericalData/IMP8/CRNC/Electrons_PT1H

Description

This data set contains hourly, spin-averaged
fluxes of electrons from the IMP8 Cosmic Ray Nuclear Composition
experiment of U. Chicago and UNH. There are fluxes of electrons
in three energy bins: 0.7-2.0, 2-12, 12-50 MeV. These fluxes
were generated at GSFC/SPDF from count rates accessible from
UNH.

Description

SFDU-formatted file describing the CRNC instrument
and the 15-min data set of count rates and pulse height data from which the
hourly rates data set was created. Division of hourly rates by geometric
factor and energy band widths yielded the hourly fluxes.
