GSFIT Data Format

GSFIT Log File Format

NOTE: Although such GSFIT/GSFITCP may appear to be traditional IDL *.sav, attempting to restore them via IDL command line using the native RESTORE procedure would only recover the first record logged in the file. To recover the full information stored in such files one may use one of the two support routines that are part of the GSFIT package
