    A PostScript rendition of gravity anomalies in file GGM2BA60.IMG in       
    the IMG directory of this archival volume.  This file shows anomalies     
    in Mercator projection over 0-180E longitude and 60S to 60N latitude.     
                                                                              
    Gravity anomalies are in milligals and are derived from Mars gravity      
    model GMM2B (also known as MGM1004D) evaluated to degree and order 60.    
    The gravity anomalies are referenced to a rotating spheroid with the      
    following constants:
