This directory contains EPAC pulse height analysis data in 1 day (24 hr)      
files. Data files are provied in both binary and ascii formats which          
contain the same information but in a slightly different format. The file     
naming convention is EV92xxx (.BIN binary) or (.TAB ascii table) where        
the xxx is the day of 1992. Each file is described by a detached PDS          
label file (.LBL).                                                            
                                                                              
In addition to the data files, the EPAC instrument team has provided          
two pieces of IDL code. The program CHANTOEN.TXT will convert EPAC            
channel numbers to energy (MeV). The program EPAC_EV.TXT reads the            
all available PHA data and generates a postscript plot file "epac-ev.ps".     
The postscript output of EPAC_EV.PRO for this data submission also            
included with this archive (EPAC_EV.PS). A second postscript file,            
(EXAMPLE.PS) shows a more fully annotated version of the output of this       
program for 170 days in the solar wind in 1998. In addition to the data,      
the annotated plot shows the theoretical traces of several atomic species     
(He - Fe) for comparison purposes.                                            
                                                                              
GIF files have been made of the postscript provided by the EPAC team by       
the PDS (EPAC_EV.GIF,  EXAMPLE.GIF) to facilitate viewing with web browsers.
