Data Set Overview
    =================
    This data set includes Voyager 2 Jupiter encounter
    magnetometer data that have been resampled at a 48.0 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

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.
