DESCRIPTION                  = "
 This file contains a digital map of the Bouguer gravity derived from 
 the JPL CERES18D model of the Ceres gravity field.  Each point gives the 
 Ceres gravity radial acceleration minus the gravity derived from 
 integration Ceres shape assuming uniform density in milligals on a 
 482.0-km x 445.9-km ellipsoid of revolution, which is close to the 
 surface of Ceres. The hydrostatic coefficients J2 and J4 are not included.
 The JGDWN_CER18D_BOU_0018 gravity acceleration is computed from the full
 CERES18D solution (from degree 2 up to degree 18).

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