  This directory contains a set of subdirectories.  Each
subdirectory has a name of the form D<yyyy_ddd> where yyyy is a year and ddd 
is a day of year.  Each of these subdirectories correspond to one of the 
subdirectories of the CALIB/VERSION_<n> directory.
  The contents of these directories are pairs of PDS data and label files.
Each pair corresponds to a UVIS observation.  The name of the file
contains the UVIS detector channel and the approximate start time of the
observation.
