These data were originally archived in the following PDS3 data set:               
GO-E-EPD-4-SUMM-EARTH2-15MIN-V1.0 (https://doi.org/10.17189/1519640).             
                                                                                  
Collection Overview                                                               
===================                                                               
                                                                                  
This collection contains 15 minute averaged rate data for all 64 EPD              
channels. The collection covers the Earth 2 encounnter data from 1992 Day 311     
through day 353.  All available motor positions except zero are included in the   
averages.                                                                         
                                                                                  
The rates reported are in units of counts/sec.  Each entry in the                 
collection is averaged over a 15 minute time span by the 'Quality Controlled      
Averaging' routine developed by Dennis Haggerty and Tom Armstrong as part of the  
Ulysses HiScale project.                                                          
                                                                                  
NOTE                                                                              
===================                                                               
Data in this collection includes only that data which has                         
valid data flag markers as a result of processing done by the Galileo             
Energetic Particles Detector Archive Processor.                                   
                                                                                  
Depending on the tools used for EPD data analysis, it is possible to encounter    
the pitch angle of the detector being substituted for the pitch angle of the      
charged particles. For example, in Figure 4 of Williams et al. (1998),            
J. Geophys. Res., 103, 17,523-17,534, the authors show a loss at 0 deg PA,        
which if viewed carefully must be at 180 deg PA. It is therefore useful to        
exercise caution with pitch angles in the EPD data, depending on how the data     
are obtained.
