  DESCRIPTION                  = "
     Derived HEND data are composed of raw counts, a background component,
     background subtracted counts and the associated timing and spatial
     information. The five raw counts fields included in the DHDs consist of
     the cumulative counts of neutrons at the detector of interest over one
     collection interval. The collection interval is approximately 19.7
     seconds, but may vary over the course of mapping. The five background
     count fields are derived from spatial data and count data collected
     during the cruise phase of the mission. The five background subtracted
     count fields are the background subtracted counts at the detector of
     interest over one collection interval. Timing and spatial data provided
     with the counts include spacecraft clock values and spacecraft geometry
     data. The sc_ev_time, utc time and spatial fields are all recorded at
     the center of the collection interval.
