The BROWSE directory contains PNG thumbnail files for browsing the data       
provided in the DATA directory.  Each file comes with a detached PDS label.   
Note that there is *not* a one to one correspondence between the DATA         
products and the BROWSE products.  Instead, BROWSE products are provided      
as yearly, quarterly or monthly overviews.                                    
                                                                              
BROWSE products are also only provided for a selected set of parameters       
in the data sets in particular the main AOCS & DMS computers. They are        
carefully chosen as being of most interest to have as thumbnails to help      
browse through the data sets and select data and periods of interest.         
                                                                              
For the EDAC dataset, Browse products have been produced for the full         
duration of the mission with the period launch to end 2013 provided in        
single yearly files and for the comet part of the mission on a quarterly      
basis. They begin when the satellite was launched in March 2004 and end       
on the 30th Sept 2016.                                                        
                                                                              
For further details of the BROWSE product implementation, please see the      
USER_GUIDE.PDF and the EAICD_HK.PDF documents in the DOCUMENT directory.      
                                                                              
The BROWSE file naming convention is defined to match with the                
<param description> part of the directory structure defined in the /DATA      
directories, i.e.                                                             
                                                                              
<parameter_id>_<YYYY>.<EXT>                                                   
or                                                                            
<parameter_id>_<YYYY_MM>.<EXT>                                                
or

where:                                                                        
<parameter_id>  is the housekeeping parameter presented                       
<YYYY>          is the year shown in the thumbnail                            
<YYYY_MM>       is the year and month shown in the thumbnail                  
<YYY_QX>        is the year and quarter shown in the thumbnail                
<EXT>           is either PNG for the browse file or LBL for the              
                corresponding PDS label file                                  
                                                                              
Note that for the EDAC browse data files, the filename used is not an         
exact copy of the PARAMETER_ID.  This is because of restrictions in the       
length of the filename.  As a result the '_AND' section of the                
parameter_id was removed for all BROWSE filenames.
