This directory contains the 15 minute particle counting rate data from        
the Energetic Particle experiment on Voyager 2 from the Jupiter encounter     
period of 1979-07-02 to 1979-08-04.  Data include scan averaged, sector       
averaged, as well as 1 hour sector summary data.                              
                                                                              
The data are stored as 3 ASCII table files (.TAB), each accompanied by a      
PDS label file (.LBL) which describes the properties of the data file.
