Data Set Overview
    =================
      Each record in the table specifies a longitude and latitude on
      Mercury and an estimate of its radius at that location, derived
      from Goldstone Solar System Radar observations.  All fields are
      separated by commas.

Overview
    ========
      Monte Carlo simulations indicate errors of about 150 meters in
      range.  The actual accuracy depends upon signal to noise ratio,
      scattering law, and the profile distance from the sub-radar
      point.
