Description

This description was generated automatically using input from the Planetary Data System.

This data set contains the thermal electron density and temperature in the PLS energy range (10-5950 eV) from Voyager 2 at Uranus 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. The moment density and temperature obtained by integrating over the entire measured distribution function are also given. This is a subset of the data set VG2-U-PLS-5-RDR-ELEFIT-48SEC which should be obtained before this data is used, since it contains information on the type of fit performed and LECP contamination of the data. Spacecraft charging may result in underestimation of thermal electron density in some regions. The first six columns are the time tag (year, day, hour, min, sec, msec), columns 7 and 8 are the total moment density and temperature, columns 9 and 10 are the fit density and temperature of the thermal electron component, and 11 and 12 are the moment density and temperature of the suprathermal electrons. Each row has the format (6I4,6E12.4). 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. (1987) and a complete instrument description can be found in bridge (1977).
