75 75 <Caveats>These data contain persistent noise signals at 0.2, 8, 16 Hz, and associated
76 76 harmonics. This noise was not observed during ground testing of the
77 77 instruments and is anticipated to be interference arising from the spacecraft.

  81 +There are errors in some of the Cassini MAG data in this data set
  82 +due to incorrect handling of leapseconds. The errors are as follows:
  83 +* 2012-07-01 00:00:00.000 - 2015-07-01 00:00:00.000 - Error : +1 s
  84 +* 2015-07-01 00:00:00.000 - 2017-01-01 00:00:00.000 - Error : +2 s
  85 +* 2017-01-01 00:00:00.000 - End of Mission - Error : +13 s
  86 +
  87 +The time tags can be corrected by subtracting the error from current time
  88 +values. This error was created during the conversion of the data from binary
  89 +to ASCII performed at the PDS/PPI node. It does not exist in the original
  90 +binary data files available from the Cassini MAG team. The PPI node will
  91 +correct this error in it's data holdings at a future date.
  92 +
  93 +
  94 +Some versions of these data were determined to contain timing errors,
  95 +including both backwards and repeated times. These timing errors have not
  96 +been corrected in the data files.
  97 +A full list of all files, and intervals containing timing errors is provided
