            <Description>Cassini RPWS Neproxy data contains all available RPWS Langmuir probe (LP) floating potentials and secondary products.
                
       Cassini RPWS Langmuir Probe proxy electron density data are derived    
      using an empirical relation between the floating potential and CAPS    
      measured densities, for the entire mission. Spacecraft potential data  
      are also derived from LP floating potential.

        <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 Ufloat proxy method for this data set is applicable only
    for densities below 5 cm^-3.  To avoid uncertainty of the transition    
    region, data are limited to radial distance beyond 7 Rs from Saturn and  
    absolute magnetic latitude above 15 degrees.  Also the data inside 10 Rt 
    from Titan are not included for the same reason.  The proxy method uses  
    the photoelectron condition directly measured by the instrument and      
    therefore not available when LP is totally in shadow.</Caveats>
