The BROWSE directory contains reduced-size, easily viewed versions of the     
Mars Express SPICAM standard data products in Portable Network Graphic format.
Browse image names are based on the PRODUCT_ID of the data product that they  
represent, following the pattern of xxx.PNG.                                  
                                                                              
The BROWSE directory follows the same naming convention as the DATA directory.
                                                                              
                                                                              
Browse files provided by the SPICAM team will have the following name:

note : For the CRUISE phase the orbit number is not applicable.               
The 5 digits will contain the day of the year of the observation (2003),      
preceeded by the letter N for the Near Earth Verification Phase, or by the    
letter C for the Interplanetary Cruise phase.
