The VG2 data directory contains 6 types of instrument data and ephemeris      
data files from the Voyager 2 Saturn encounter.  These instruments include:   
1) CRS, 2) LECP, 3) MAG, 4) PLS, 5) PRA, and 6) PWS.  The ephemeris data      
directory is named as EPHEM.  Data in this directory covers the time period   
from 1981-08-19 to 1981-09-04.  Individual data sets may have different       
start and stop times of the coverage. Please refer to the following list      
for information on each instrument data files, which also contain INFO.TXT    
files, that describe the data file contents.
