COSPIN/LET 10 min Average 0.9-1.2 MeV Proton Spin-Averaged Fluxes (L1)
ParameterKey
L1
Description

10 min Average LET spin-averaged proton fluxes between 0.9 and 1.2 MeV

Caveats
Rate channel L1 (which nominally responds to protons in the energy range 0.9-1.2 MeV) is derived from a single detector measurement, and as such is sensitive to penetrating particles which lose part of their energy in the detector. The background contribution depends on the energy spectrum of the incident particle population, being negligible for (differential) energy spectral slopes of -3.5 or steeper, increasing to 80% of the total counts for a slope of -1.0 or harder.

As in the case of L1, the background contribution depends on the energy spectrum of the incident particle population, being negligible for (differential) energy spectral slopes of -2.0 or steeper, increasing to 80% of the total counts for a slope of +0.75 or harder.
