      <description>This is the collection of Radio Science Orbit Data File (ODF) data products acquired  
            during the MESSENGER mission. 
            These ODF files were produced by the NASA/JPL Multi-Mission Navigation Radio
            Metric Data Conditioning Team for use in determining spacecraft trajectories, 
            gravity fields affecting them, and radio propagation conditions.</description>

        <description>The data files in this collection have been migrated from PDS3 to PDS4.
                      The data files have not been changed; only a new PDS4 label was created
                      as part of the migration process.</description>

      <comment>Reference document for the Orbit Data File (ODF) data.
        For data collected earlier or later than this document, consult other
        document products in the same collection.

        Orbit Data Files (ODFs) were
        produced by the NASA/JPL Multi-Mission Navigation Radio
        Metric Data Conditioning Team for use in determining
        spacecraft trajectories, gravity fields affecting them,
        and radio propagation conditions.  Each ODF consists of
        many 36-byte logical records, which fall into 7 primary
        groups plus an End-of-File Group.  An ODF usually
        contains most groups, but may not have all.  The first
        record in each of the 7 primary groups is a header
        record; depending on the group, there may be from zero
        to many data records following each header.</comment>
