Description
The Cassini RPWS Langmuir Probe Sweep @ Saturn data set contains thermal
plasma parameters derived from Langmuir Probe voltage sweeps
acquired in the vicinity of Saturn during the entire Cassini
mission. Data are the results of the Orbital Motion Limited analysis for each
calibrated sweep of the Langmuir probe receiver (LPR) of the RPWS

Caveats
Occasional RPWS Langmuir probe voltage sweeps have interference in
individual sweep samples. These samples have been filtered away
before analysis and should not pose a problem for the delivered
output parameters. The RPWS HFR receiver produces interference
signals in the LPR in certain negative bias voltage ranges. These do
not affect the analysis on the electron (positive bias voltage
side), and cause otherwise no significant error in the derived ion
parameters.
Thermal electron output data will usually not be available, due to
photoelectron current contamination, for number densities below 1
cm^-3 and/or for temperatures above 10eV, i.e. outside the
ionosphere of Titan. Data < 1 cm^-3 and/or > 10 eV should be
regarded as uncertain. Electron temperatures below 0.03eV should be
regarded as uncertain, as the rms electric field surface variability
of the spherical TiN coated probes is 0.015eV, and the number of
sweep samples used for the temperature estimation becomes small (4-5
samples out of 1024 samples over +/-4V).
