      instrumentation consisted of a double CVF with a liquid                 
      nitrogen cooled InSb photometer.  The short half of the CVF             
      (denoted DCS) covered the region from ~0.8 - 1.6 microns with           
      3% resolution, and the long half (denoted DCL) covered                  
      ~1.5 - 2.5 microns at 5% resolution.  For this spectrum, every          
      other position of the CVF was sampled for the DCS data."
