END_OBJECT = TEXT END ============================================================================== This volume was produced for the Planetary Data System (PDS) at the Planetary Plasma Interactions (PPI) Node. The data acquired from the Cassini MAG team at Imperial College. Data products were generated, and the volume assembled at the PDS-PPI node at UCLA. The PDS assumes no legal liability for errors found in this data set. All users of the data are encouraged to verify their correctness prior to submitting any to publications or other work based on these data. Please report any errors found in the data or documentation of this data set to the PDS Operator at the PDS-PPI node: Email pds_operator@igpp.ucla.edu Telephone (310) 206-6073 An updated version of this file is maintained online at the Planetary Plasma Interactions Node of the Planetary Data System. The PDS standards do not specify where to store the required MD5 checksum file for a volume. We have placed it in the root dircetory of the volume with the file name "CHECKSUMS.TXT". This may be considered invalid by some verifiers. ============================================================================== ------------------------------------------------------------------------------ These data contain persistent noise signals at 0.2, 8, 16 Hz, and associated harmonics. This noise was not observed during ground testing of the instruments and is anticipated to be interference arising from the spacecraft. Removal of these signals is at the user's discretion. 2024-09-16 There are errors in some of the Cassini MAG data in this data set due to incorrect handling of leapseconds. The errors are as follows: Time Interval Error ------------------------------------------------- ----- 2012-07-01 00:00:00.000 - 2015-07-01 00:00:00.000 +1 s 2015-07-01 00:00:00.000 - 2017-01-01 00:00:00.000 +2 s 2017-01-01 00:00:00.000 - End of Mission +3 s The time tags can be corrected by subtracting the error from current time values. This error was created during the conversion of the data from binary to ASCII performed at the PDS/PPI node. It does not exist in the original binary data files available from the Cassini MAG team. The PPI node will correct this error in it's data holdings at a future date. ------------------------------------------------------------------------------ ------------------------------------------------------------------------------ Data Timing Errors Some versions of these data were determined to contain timing errors, including both backwards and repeated times. These timing errors have not been corrected in the data files. However, any timing errors that may be present in a data file are noted in the PDS label file that accompanies it. A full list of all files, and intervals containing timing errors is provided at: /DOCUMENT/DATA_QUALITY/FGM_FULL_TIMING_ERRS.CSV. A more detailed description of the timing errors is included in the data set catalog file: /CATALOG/CO_MAG_CAL_FULL_DS.CAT. ------------------------------------------------------------------------------
