 DESCRIPTION                 = "Numerical shape model of M2 Deimos, derived   
 solely from Viking Orbiter data.  It has uncertainties of ~400 m in much of  
 the region longitude 200-355 degrees.  This shape model consists of a grid   
 with points every 5 degrees in latitude and longitude, with a radius in km   
 associated with each point.  Model is written with both 0 and 360 longitude  
 entries.  Coordinates are planetocentric.  See Thomas 1993 for details of    
 shape model.                                                                 
                                                                              
 Deimos rotates synchronously with its orbital period.  Spin pole: RA= 316.65,
 Dec=53.53 J2000 in degrees.  W = 79.41 + 285.1618970d in degrees, where d is 
 the number of days from the standard epoch (JD 2451545.0).
