This data set contains the ion densities and temperatures
      along with formal 1 Sigma errors obtained from Voyager 2
      PLS data (voltage range 10-5950 eV/Q) at Uranus by fitting
      the measured spectra with isotropic Maxwellian
      distributions. Up to three isotropic proton components
      (warm, hot and intermediate) were used to match the
      observations. The plasma was assumed to be rigidly
      corotating. Uncertainties in plasma parameters are a factor
      of 2 in the charging region from 19:39-21:58 on day 24, less
      than 20% elsewhere. A complete description of this data set
      is given in McNutt et al. (1987) and Selesnick and McNutt
      (1987).

    DATASET PARAMETERS:

    Each data record consists of six lines:

     1.   Time of measurement
          Mode (A3): L or M.
     3-6. Cup identifier (A1): A, B, C, or D.
          Number of sets of channels used in fit (I3).
          Beginning and ending channel of each set (2I4
          repeated for each set).
     7-19.Density (CM-3) and 1 sigma uncertainty for first
          fit component (2E10.3).
          Same for second fit component (2E10.3).
          Same for third fit component (2E10.3).
          Thermal speed (KM/S) and 1 sigma uncertainty for
          First fit component (2E10.3).
          Same for second fit component (2E10.3).
          Same for third fit component (2E10.3). Values of
      1.E32 indicate that the parameter could not be obtained
      from the data using the standard analysis technique.
      Additional information about this dataset and the
      instrument which produced it can be found elsewhere in this
      catalog. An overview of the data in this data set can be
      found in McNutt et al. (1987) and Selesnick and McNutt
      (1987) and a complete instrument description can be found
      in Bridge (1977).

This data set provides a reliable estimate of the ion
      density and energy in the PLS energy range (10-5950 eV)
      throughout the region where data is provided. All ion
      components are fit with Maxwellians although they may not
      be Maxwellian in nature. Formal 1 sigma uncertainties for
      the derived densities and thermal speeds are given in the
      data set and range from a few to 20%. Underestimates of ion
      density and temperature due to ions outside the PLS energy
      range are less than 10%.
