   This document provides an overview of this volume of the Tempel 1          
   shape models, including a complete listing of the volume contents.         
                                                                              
   This volume contains the plate model that describes the basic shape        
   of the nucleus of comet 9P/Tempel 1.  Two different versions of the        
   plate model are included, one defined in cartesian coordinates             
   and one in planetocentric coordinates.  See the DATASET.CAT file           
   in the CATALOG directory for information about how the models were         
   derived.
