There are 2 data sets for the EPD instrument, Low-Rate Science (LRS) and      
Real-time (RTS).  The LRS data is obtained at flybys, while the RTS data      
is collected during orbit.   The LRS data is contained in the SATELLITES      
directory while the RTS data is in the SURVEY directory.  Each of these       
is subdivided according to target or orbit.                                   
                                                                              
For each set of data, there is a corresponding "corrected" set prefixed       
with "C_".  These corrected data have been adjusted for minute gaps in between
detector cycles.                                                              
                                                                              
The LEM_V5 directory contains code and input data necessary to transform ion  
data into the particle rest-frame.                                            
                                                                              
Additional information about these data is available in the CATALOG           
and DOCUMENT directories off the root of the archive volume. Files on

Spacecraft Attitude/Orientation data can be found in the GEOMETRY directory   
off of the root of the archive volume. Spacecraft trajectory data in a        
variety of coordinate systems is located in the DATA/TRAJECT directory.
