The BROWSE directory contains 20-day energy per charge spectrograms based     
upon the CHEMS Pulse-Height (PHA) data. Directory organization and naming     
follows the same conventions used in the DATA area of this volume.            
Specifically, the images are divided by species (H+, He+, H2+, He++, O++, and 
W+ or water ion group). Each of the species directories is subdivided by year.
                                                                              
Each PDF file is accompanied by a PDS label file which describes the contents 
of the images.
