            <description>This collection contains
                spectrogram representation of the summation
                of the shaped count rates in detectors 0-10 except detector 3.  The
                counts are binned in time (120 s) and pitch angle (22.5 deg).   
                Constant normalization factors and background subtractions 
                (see  SIS for Table) have been applied to these rates.</description>
