   <li> AMDA Parameters: Electron Density, Contrast<br/>
         Contrast varies from 0 to 1.<br/> Contrast = -1  and Uncertainty = 0 means that electron density has been determined
         not from WHISPER data.
   <li> Argument /con[trast]  while plotting density adds <a href="help/parameters/doc/whisper_contrast.png" TARGET=_BLANK> contrast color bar</a> to density plot.
   <li> Argument /unc[ertainty] while plotting density adds <a href="help/parameters/doc/whisper_unc.png" TARGET=_BLANK> errors </a> to density plot.
        Contrast = -1 corresponds to Error = 0.
   <li> You may use <a href="help/parameters/doc/whisper_contrast_unc.png" TARGET=_BLANK> both arguments</a> for the same density plot  
   <li> Read <a href="http://www.springerlink.com/content/q3172663667431p2/" TARGET=_BLANK>detailed description</a> of electon density determination.
