DESCRIPTION                  = "
 This file contains a digital map of the Mars gravity anomaly formal
 uncertainty derived from the error covariance of the spherical harmonic 
 coefficients of the NASA GMM-3 gravity field. Each point gives the Mars 
 gravity anomaly error in milligals, which is the error of the model 
 gravity on the grid defined from -89 S to 90 N and 0 E to 359 deg E.
 The GMM3_120_ANOMERR_100 gravity anomaly error map is computed from a 
 truncated GMM-3 solution (from degree 2 up to degree 100).

 This work was completed by A. Genova as a postdoctoral scientist at NASA
 Goddard Space Flight Center as part of the MRO Gravity Science Team, and 
 under the direction of M.T. Zuber and F.G. Lemoine. The reference for the 
 GMM-3 gravity field is GENOVAETAL2016, under review by Icarus."
