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