    A PostScript rendition of gravity anomalies in file GGM1025A.IMG in       
    the IMG directory of this archival volume.  This file shows anomalies     
    in Mercator projection over 360 degrees of longitude and in polar         
    projection poleward of 70 degrees latitude.                               
                                                                              
    Gravity anomalies are in milligals (1 milligal = 0.01 mm/s) and are       
    derived from Mars gravity model MGM1025 evaluated to degree and order 66. 
    The gravity anomalies are referenced to a rotating spheroid with the      
    following constants:
