                A data file that contains calibration information as a function of time,
                and that indicates which calibration data values (offsets and sensitivity
                matrices) are to be applied to raw vector helium magnetometer (VHM) data, 
                according to its time of origin.

                    This product, 04182_04366_VHM_CAL.FFD, was originally released as part
                    of the PDS3 CO-E/SW/J/S-MAG-2-REDR-RAW-DATA-V2.0 dataset. The metadata
                    have been migrated to PDS4. The data themselves are unchanged.

                This file is required as an input for the CAL02.EXE
                application, and is updated with each new archive-volume delivery, so as
                to include a complete time history of calibration information. Any
                revisions to calibration history will be noted in the file's label.
