ResourceID
spase://CNES/NumericalData/CDPP-AMDA/Cassini/RPWS/cass-rpws-titan

Description
The Cassini RPWS Langmuir Probe Sweep @ Titan data set contains thermal plasma parameters derived from Langmuir Probe voltage sweeps acquired in the vicinity of Titan 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).
