         LRO CRaTER Document Collection. Contains the following files and
         their PDS labels:

         errata.txt 
           An errata file describing errors and caveats pertaining to the
           data. This file is based on information about the PDS3 data.
           Because the PDS4 bundle is based on the PDS3 data sets, this 
           document also is relevant to the PDS4 data.

         data-cal-desc.txt
           A document describing the calibrated (Level 1) data. This document
           is based on the *DS.CAT files from the PDS3 data sets.

         data-der-desc.txt
           A document describing the derived (Level 1) data. This document
           is based on the *DS.CAT files from the PDS3 data sets.

         VOLSIS.PDF
             The PDS3 SIS in PDF format. This document describes the PDS3 data set
             that was converted into the PDS4 bundle.
