Data Set Overview
    =================
      This data set includes Voyager 2 Jupiter encounter magnetometer
      data that have been resampled at a 9.6 second sample rate.  The
      data set is composed of 6 columns: 1) ctime - this column
      contains the data acquisition time.  The time is always output
      in the ISO standard spacecraft event time format
      (yyyy-mm-dd-Thh:mm:ss.sss) but is stored internally in Cline
      time which is measured in seconds after 00:00:00.000 Jan 01,
      1966, 2) br - this column contains the radial component of the
      magnetic field, 3) bphi - this column contains the phi
      component of the magnetic field, 4) btheta - this column
      contains the theta component of the magnetic field, 5) bmag -
      this column contains the magnitude of the magnetic field, 6)
      flag - a flag value that indicates either software error or
      spacecraft hardware interference reduced confidence in this
      record (flag value of 1 is bad , 0 is good or unchecked).  All
      magnetic field observations are measured in nanoTeslas.  The
      coordinate system for this dataset is Minus System III.  All of
      the magnetic field data are calibrated (see the instrument
      calibration description for more details).  The Jupiter System
      III coordinate system is defined in Dessler 1983 and the
      reference documents for this dataset are: Ness et al, 1979A
      Lepping et al, 1981 Connerney,Acuna,Ness, 1981
      Behannon,Burlaga,Ness, 1981

Overview
    ========
      This dataset contains some data gaps and spikes.  The dataset
      does contain a flag value which has been provided by the PI
      (Norman Ness) that indicates whether or not a particular record
      has been contaminated by software error or by spacecraft
      interference ( a flag value of 1 indicates a bad value, 0
      indicates that the record has either not been evaluated or is
      good).  Some records that are obviously contaminated have not
      been flagged.  The hourly summary data will show a
      contamination code and data quality code of 2 when data in the
      hour have not been flagged but are obviously in error and a
      contamination code of 1 when the hour contains flagged records.
