DESCRIPTION                  = "
 This file contains a digital map of the Ceres geoid derived from 
 the JPL CERES18D spherical harmonic model of the Ceres gravity field.  
 Each point is the Ceres geoid height in meters above a reference 
 ellipsoid (semi-major-axis = 482.0 km, GM = 62.6273588067 km**3/s**2,
 flattening = 0.074896, and rotation rate = 0.000192340387006239 rad/s).

 The JGDWN_CER18D_GEOID_0018 is computed from the CERES18D 
 solution (from degree 2 up to degree 18).

 The map is produced by Dawn Gravity Team (Alex Konopliv, Ryan Park, 
 Sami Asmar) at JPL."
