Data Set Overview
    =================
      THIS DATA SET CONTAINS THE THERMAL ELECTRON DENSITY AND
      TEMPERATURE IN THE PLS ENERGY RANGE (10-5950 EV) FROM VOYAGER 1
      AT SATURN DERIVED BY FITTING THE LOW ENERGY ELECTRON COMPONENT
      WITH A MAXWELLIAN DISTRIBUTION, AND THE MOMENT DENSITY AND
      TEMPERATURE OF THE HOT ELECTRONS CALCULATED AFTER THE SIGNAL
      FROM THE THERMAL COMPONENT IS SUBTRACTED FROM THE ELECTRON
      SPECTRA.  IT IS A SUBSET OF THE DATA SET
      VG1-S-PLS-5-ELE-FIT-96.0SEC WHICH SHOULD BE OBTAINED BEFORE
      THIS DATA IS USED.  SPACECRAFT CHARGING MAY RESULT IN FACTOR OF
      2-3 ERRORS IN THE THERMAL ELECTRON DENSITY.  THE FIRST SIX
      COLUMNS ARE THE TIME TAG (YEAR, DAY, HOUR, MIN, SEC, MSEC),
      COLUMN 7 AND 8 ARE THE FIT DENSITY AND TEMPERATURE OF THE
      THERMAL ELECTRON COMPONENT, AND 9 AND 10 ARE THE MOMENT DENSITY
      AND TEMPERATURE OF THE SUPRATHERMAL ELECTRONS.  EACH ROW HAS
      THE FORMAT (6I5,4E12.4).  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 SITTLER ET AL.  (1983) AND A COMPLETE
      INSTRUMENT DESCRIPTION CAN BE FOUND IN BRIDGE (1977).

      Description
      -----------
        A derived parameter giving an indication of the mean A
        derived parameter equaling the number of electrons per unit
        volume over a specified range of electron energy.
        energy/electron, assuming the shape of the electron energy
        Different forms of electron density are derived spectrum to
        be Maxwellian (i.e.highest entropy shape).  Given
        distinguished by method of derivation (Maxwellian fit, that
        the electron energy spectrum is not exactly Maxwellian,
        method of moments) or by the some selection criteria (ie.,
        the electron temperature can be defined integrally (whereby
        the mean energy obtained by integrating under the actual hot
        electron and cold electron density).  In general, if more
        electron energy spectrum is set equal to the integral under
        than one electron component is analyzed, either by moment or
        fit, a total density will be provided which is the sum of a
        Maxwellian, where the temperature is a free parameter for the
        electron densities.  If the electron do not have a which to
        solve), or differentially (whereby the slopes of Maxwellian
        distribution the actual distribution can be the actually
        electron energy spectrum at various energies are matched to
        the slopes of a corresponding Maxwellian).  represented as
        the sum of several Maxwellians, in which case the density of
        each Maxwellian is given.  The temperature parameter is often
        qualified with a range of applicable energies.  temperatures
        can be angularly anisotropic.  If the electrons do not have a
        Maxwellian distribution the actual distribution can be
        represented as the sum of several Maxwellians, each with a
        separate temperature.

Overview
    ========
      THIS DATA SET PROVIDES AN ESTIMATE OF THE ELECTRON PARAMETERS
      IN THE PLS ENERGY RANGE (10-5950 EV).THE THERMAL ELECTRON
      DENSITY MAY BE UNDERESTIMATED BY FACTORS OF 2-3 IN SOME REGIONS
      DUE TO NEGATIVE SPACECRAFT CHARGING.  THERMAL ELECTRON
      PARAMETERS ARE ALSO UNRELIABLE INSIDE SIX KRONIAN RADII WHERE
      ELECTRON TEMPERATURES ARE COLD AND IN THE OCCULTATION REGIONS.
      HOT ELECTRONS ARE RELATIVELY UNDISTURBED BY CHARGING AND THESE
      PARAMETERS HAVE UNCERTAINTIES OF LESS THAN 20%.
