                This collection contains Mars Global Survery (MGS) Radio Science Digital Map 
                files of image representations for gravity anamoly models. These files contain 
                gridded representations of gravity anomalies with respect to an evaluation of the             
                specified model to certain degrees and orders. The data in this collection cover
                1997-09-12T00:00:00Z - 2002-05-27T23:59:59Z.

                    This is the original version of this collection in PDS4.
                    It was migrated to PDS4 from the PDS3 data set MGS-M-RSS-5-SDP-V1.0.
