This data set includes data from the Low Field Magnetometer (LFM)
          in the solar wind during the Uranus encounter. The
          encounter data (1986-01-24T07:00:00  -> 1986-01-25T04:00:00)
          have been averaged from the 1.92 second averaged data
          to a 9.6 second resampled rate and
          are provided in the Uranus Longitude (U1) coordinate system.
          Magnetometer data in the solar wind are given in Heliographic
          coordinates and are also available in a separate dataset.
          The dataset consists of the following columns:
           1) ctime (decimal seconds since 1966-01-01T00:00:00.000),
           2) pdstime (ISO standard time format),
           3-5) spacecraft clock (m65536,m60,fds-line),
           6) magnetometer id (1 = LFM, 2 = HFM),
           7) Br (radial component),
           8) Bphi (longitudinal component),
           9) Btheta (colatitudinal component),
          10) Bmag  (magnitude of the average components),
          11) avg_Bmag (average of the magnitude of the raw components),
          12) Lambda (longitude = tan^-1(Bt/Br)),
          13) Delta (latitude = sin^-1(Bn/avg_Bmag) ),
          14-16) rms vector (Pythagorean root mean square deviation
               of the component averages),
          17) npts (number of points in average),
          18) flag a character string which indicates software or
              s/c hardware intervention which reduces confidence
              in the data (NULL flags represent 'good' data).


          The U1 coordinate system is a non-inertial spherical coordinate
          system that rotates with Uranus with a period of
          17.24 hours. The system components are:
          R     - Radial along the Uranus-S/C line, positive away from Uranus,
          Phi   - east longitudinal component,
          Theta - colatitudinal component.


              An ancillary data file containing the derived spacecraft
          magnetic field is provided with this data at a 48 second
          sample rate. These data provide zero level offsets used in
          the data processing. S/C field data is provided in spacecraft
          coordinates.

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.
