                Cassini magnetic-field 1 second averages, from the Fluxgate
                Magnetometer (FGM), from 1999-08-16 - 1999-09-15, in GSE coordinates. 
                GSE coordinates consist of X (Earth to Sun), Y (completes the right handed set), and Z (perpendicular to
                the ecliptic plane).

      GSE coordinates consist of X (Earth to Sun), Y (completes the right 
      handed set), and Z (perpendicular to the ecliptic plane).
      
      These MAG data were averaged from the full-resolution MAG data at the
      PDS PPI node at UCLA. The full-res MAG data were processed
      (calibrated, rotated into GSE coordinates) by the Cassini MAG team at
      Imperial College and are archived as part of the data set:
      CO-E/SW/J/S-MAG-3-RDR-FULL-RES-V1.0. The full-res data were provided
      to PDS by the MAG team Co-I at UCLA. Trajectory and the number of
      points in the average were added at the PDS/PPI node. Note that for
      some of the data files associated with the PDS3 data set it was necessary
      to remove mistime-tagged data present in the full-res dayfiles prior
      to averaging. A complete list of full-res data files containing
      mistime-tagged intervals is provided in the file
      FGM_FULL_TIMING_ERRS.CSV, which is included in the
      'Cassini Bundle, document-mag collection.'
      
      For more information on this data set please refer to the PDS catalog
      file for this data set (CO_MAG_CAL_1SEC_DS.CAT).
