EXTRAS Directory Contents                                                     
                                                                              
                                                                              
The EXTRAS directory provides a browse facility implemented as a website      
for viewing a thumbnail and a full-frame JPEG image for each data product     
in this dataset.  The BROWSE subdirectory contains daily folders that         
include the JPEGs and an INDEX.HTML file to facilitate displaying the         
JPEGs along with direct links to the associated FITS data file and its        
PDS label.                                                                    
                                                                              
The thumbnail files are the full-frame JPEG images resized to a smaller,      
consistent width and height of 80x40 pixels.  The brightness of some JPEGs    
may differ from the corresponding FITS images because the same stretch was    
always used.
