  DESCRIPTION                  = "

     The SGS product contains sums of corrected gamma spectra with
     ancillary data. The data has been summed spatially over a 
     5 degree by 5 degree grid and temporally over intervals of 15
     degrees of solar longitude.

     The SGS product data is presented in a tables corresponding to 
     the 36 latitude bands of the 5x5 degree grid.

     This file is for the band centered at -17.5 degrees latitude.
    
     Within each band, longitude increases eastward from the cell
     centered at 2.5 degrees east longitude to the cell centered at 
     357.5 degrees east longitude.
