| Data Set Abstract |
This data set contains electron
parameters in the PLS energy range (10-5950 eV) at Uranus during the
Voyager 2 encounter. Parameters are calculated in several ways. Total
moment density and temperature are given. Each electron spectrum is
also fit with a thermal component and 1-3 hot components depending on
how many Maxwellians are needed to fit the entire distribution. The
moment density and temperature of the hot component is calculated
after the thermal component is subtracted from the spectrum. The
CHI-Square value for each fit is given. The spacecraft charge is not
calculated consistently, and may result in factor of 2-3 errors in the
thermal electron density. Data is unreliable inside 5 RU and in the
occultation regions. At Uranus measurements were taken using both a
long and a short integration time. Each 48 SEC measurement frame
contained either an E1-Short and an E2-Long measurement or an
E2-Short and an EI-Long. To reduce systematic errors, complete
electron spectra were obtained only by combining two long or two short
spectra. The instrument threshold is at a density of about 0.001
CM-3; thus fits which yield data close to this value should be treated
with caution. Flags in the data indicate whether the full analysis
could be performed and if the data was contaminated by LECP stepping.
A complete description of this data set is in Sittler et al. (1987). |
