 DESCRIPTION                 = "Numerical model of 433 Eros, derived          
  solely from NEAR-SHOEMAKER data.  This model comprises a grid with points   
  every two degrees in latitude and west longitude, and four data             
  associated with each point.  The model is written with both 0 and 360       
  longitude entries.  Coordinates are planetocentric.                         
                                                                              
  N.B. In this RGST-EROS-2001012 product, some radii starting from the model  
  center intersect the surface in more than one point.  This happens mostly   
  around 160 degrees west longitude.  That means that the RGST format used    
  in this product is not able to adequately represent the shape model's       
  surface.  Caveat emptor.  If this is an issue, users may use one of the     
  plate models.  See the catalog file, erossmds.cat, for this data set.
