... INTRODUCTION This data set contains fluxes and pitch angles (relative to measured magnetic field) of protons and electrons as measured in the lower half of the energy steps of the electrostatic analyzers, that is, at "<10 ev," 40 eV and 0.76 keV, 60 eV and 1.2 keV, and 100 eV and 1.8 keV. ... In the data files the values of the particle number flux is given in the data columns in units: particles per square cm per second per steradian per keV. ... FILES AND FORMAT DESCRIPTION 3.1. ...
