Description

This data set consists of a set of daily files
with GIF-formatted spectrograms displaying color coded ion flux levels
as functions of time and of energy level, in each of 4 look-direction
quadrants, over the energy range of ~150 eV/q to 45 keV/q. Also
displayed is a single omni-directional spectrogram for electrons
in the same energy range. ISEE position data is listed once every
every four hours across the time axis.
