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      
either as quarterly or monthly overviews.                                     
                                                                              
BROWSE products are also only provided for a selected set of parameters       
in the data sets, 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 HGA/APM dataset, Browse products have been produced solely for the
comet phase of the mission. They begin when the satellite comes out of 
hibernation in Jan 2014 and continue on a 3 monthly (QX - see below)
basis until 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

<parameter_id>  is the housekeeping parameter presented                       
<YYYY_MM>       is the year an 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
