Data Set Overview
      =================
      Instrument P.I.       : John D. Richardson
      Data Supplier         : John D. Richardson
      Data sampling rate    : 96 seconds
      Data Set Start Time   : 1980-11-11T23:00:46.104Z
      Data Set Stop Time    : 1980-11-12T02:55:23.545Z

      This data set contains Voyager 1 plasma fit data from Saturn's
      magnetosphere. The fit parameters assume a convected isotropic
      proton Maxwellian distribution. Use of fit parameters is recommended
      as these are normally more accurate.  Since only the first 72 or last
      72 energy/charge channels are telemetered to Earth from each M-mode
      spectra, derived parameters change significantly only every other set
      of spectra so the effective time resolution is 96 second.

      Parameters
      ==========

      Data Set Parameter 'ION DENSITY'
      --------------------------------
      Data Set Parameter Name        : ION DENSITY
      Data Set Parameter Unit        : CM**-3
      Sampling Parameter Name        : TIME
      Sampling Parameter Unit        : SECOND
      Minimum Sampling Parameter     : UNK
      Maximum Sampling Parameter     : UNK
      Sampling Parameter Interval    : UNK
      Minimum Available Sampling Int : UNK
      Noise Level                    : UNK

      A derived parameter equaling the number of ions per unit
      volume over a specified range of ion energy, energy/charge,
      or energy/nucleon. Discrimination with regard to mass and or
      charge state is necessary to obtain this quantity, however,
      mass and charge state are often assumed due to instrument
      limitations.

      Many different forms of ion density are derived. Some are
      distinguished by their composition (N+, proton, ion, etc.) or
      their method of derivation (Maxwellian fit, method of
      moments). In some cases, more than one type of density will
      be provided in a single data set. In general, if more than
      one ion species is analyzed, either by moment or fit, a total
      density will be provided which is the sum of the ion
      densities. If a plasma component does not have a Maxwellian
      distribution the actual distribution can be represented as
      the sum of several Maxwellians, in which case the density of
      each Maxwellian is given.

      Data Set Parameter 'ION THERMAL SPEED'
      --------------------------------------
      Data Set Parameter Name        : ION THERMAL SPEED
      Data Set Parameter Unit        : KM/S
      Sampling Parameter Name        : TIME
      Sampling Parameter Unit        : SECOND
      Minimum Sampling Parameter     : UNK
      Maximum Sampling Parameter     : UNK
      Sampling Parameter Interval    : UNK
      Minimum Available Sampling Int : UNK
      Noise Level                    : UNK

      A measure of the velocity associated with the temperature of
      the ions. It is formally defined as the Ion Thermal Speed
      squared equals two times K (Boltzmann's constant) times T
      (temperature of ion) divided by M (ion mass). Each component
      of a plasma has a thermal speed associated with it.

      Data Set Parameter 'ION VELOCITY'
      ---------------------------------
      Data Set Parameter Name        : ION VELOCITY
      Data Set Parameter Unit        : KM/S
      Sampling Parameter Name        : TIME
      Sampling Parameter Unit        : SECOND
      Minimum Sampling Parameter     : UNK
      Maximum Sampling Parameter     : UNK
      Sampling Parameter Interval    : UNK
      Minimum Available Sampling Int : UNK
      Noise Level                    : UNK

      A derived parameter giving the average speed and direction of
      motion of a plasma or plasma component. The velocity can be
      obtained by taking the first moment of the distribution
      function or by simulating the observations with some known
      distribution function, usually a Maxwellian, to the
      distribution. Velocities are given in Heliographic (RTN)
      coordinates:

        R is radially away from sun,
        T is in plane of sun's equator and positive in the direction
          of solar rotation
        N completes right-handed system
