GEOMETRY Directory Contents                                                   
                                                                              
                                                                              
The GEOMETRY directory contains files intended to provide information on      
the relative positions of Rosetta, the Sun and the target body, and also the  
orientation of Rosetta and the MIRO beams.  In general, the files only cover  
the periods in which MIRO acquired significant data for the target body.  The 
files are table files (*.TAB), whose contents are explained by the header     
information in the label (*.LBL) files corresponding to each *.TAB file.      
                                                                              
The following table files are present:                                        
                                                                              
ESB1_EARTH_CA_GEOM.TAB - observations of Earth, covering 45 minutes around    
closest approach, with a time resolution of 3 seconds.  This file contains an 
item not present in the other tables, the velocity along the line of sight of 
the sub-millimeter boresight (VLOSSMM);  this item is identical to the radial 
velocity for nadir pointing, which is normally used, but in this observation  
the boresight was kept fixed (pointing at the Moon).                          
                                                                              
ESB1_EARTH_2_GEOM.TAB - covering about two days of Earth observations, with a 
time resolution of 10 minutes.                                                
                                                                              
ESB1_MOON_1_GEOM.TAB - covering about 26 hours of Moon observations, all      
prior to closest approach to Moon, with a time resolution of 10 minutes.      
                                                                              
ESB1_MOON_2_GEOM.TAB - covering about two hours of Moon observations, starting
a day after closest approach to Moon, with a time resolution of 10 minutes.
