            <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</Description>

        <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 &lt; 1 cm^-3 and/or &gt; 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).  </Caveats>
