      <description>This data set contains a table of readings from the Traverse Gravimeter   
        Experiment performed during the Apollo 17 mission.  The gravimeter,       
        which recorded relative measurements of the local gravitational field     
        at the lunar surface, was manually run by the astronauts near the         
        Lunar Module landing site.  The data table includes 23 valid gravity      
        values, with calibrations and corrections, that were obtained from 12     
        to 14 December 1972.  Supporting documentation includes the Apollo 17     
        Traverse Gravimeter Experiment Final Report.</description>
