The VG2 directory contains 7 types of Voyager 2 instrument and ephemeris data files from the Saturn encounter period. These instruments include: 1) CRS, 2) LECP, 3) MAG, 4) PLS, 5) PRA, and 6) PWS. The spacecraft position data are stored in a directory named EPHEM. Please refer to the following list of directories for information on each instrument data files, which also contain INFO.TXT files, that describe the directory file contents.
