The radiation monitor file contains count rates in different energy ranges of incident electrons and protons. These are measured by a Low energy detector and a High energy detector. The columns, contained in the RMECX1 extension, are denoted by NLE for count rates from the Low energy detector and NHE from the High energy detector.

NLEO: The count rate accumulated over all 256 channels in the low energy detector, which measures: Electrons: from 130 Kev to 1.5 MeV and Protons: from 1 MeV to 4.5 MeV
NLE1: The count rate accumulated from channel 4 to channel 65 in the low energy detector, which measures: Electrons: from 160 Kev to 1 MeV and Protons: from 1 MeV to 1.5 MeV
NLE2: The count rate accumulated for channels from 66 to 255 inclusive of the low energy detector, which measures: Electrons: from 1 Mev to 1.5 MeV and Protons: from 1.5 MeV to 4.5 MeV
NHEO: The count rate accumulated over all 256 channels in the high energy detector, which measures: Electrons: from 1 Mev to 1.75 MeV and Protons: from 8 MeV to 40 MeV
NHE1: The count rate accumulated from channel 5 to channel 25 in the high energy detector, which measures: Electrons: from 1 Mev to 1.3 MeV and Protons: from 8.7 MeV to 9 MeV
NHE2: The count rate accumulated for channels from 26 to 255 inclusive of the high energy detector, which measures: Electrons: from 1.3 Mev to 1.75 MeV and Protons: from 9 MeV to 37 MeV
NHEC: represents the full counts of the spectrum "coincidence" accumulated on all 256 channels of the high energy detector, which measures: Electrons: from 0.5 Mev to 2.5 MeV and Protons: from 12.5 MeV to 100 MeV

Optionally, the spectral parameters may be written into the RMESX1 extension. Spectra are produced either every 512 seconds (SLOW mode) or every 4 seconds (FAST mode). These are stored as COUNTS in the columns: SPLE (low energy detector spectrum), SPHES (high energy detector spectrum) and SPHEC (high energy detector coincidence spectrum).
