   This document provides an overview of the Rosetta Lander ancillary data    
   set for comet phase, including a complete description of the volume        
   structure.                                                                 
                                                                              
   Additional documents included on this archive (DOCUMENT diretory)

   This data set contains navigation, related observation geometry            
   and other ancillary data for the ROSETTA Lander.                           
   See the file ``MISSION.CAT'' in the ``/CATALOG'' directory for a           
   description of the mission and the file ``INSTHOST.CAT'' in the            
   same directory for a description of the spacecraft.                        
                                                                              
   The Lander trajectory, sun direction are provided by SONC FD team using    
   RMOC (comet ephemeris an rotation) data, gravity model from GRGS (Groupe   
   de Recherche de Geodesie Spatiale), shape models from  OSIRIS. The Lander  
   attitude is derived from ROMAP data.
