CLEV
Type: Adverb  (Real)
Use:  The absolute value of the level to use an as increment in
      determining contour levels.  Contour levels(n) =  CLEV*LEVS(n).
Null Value:  None
Tasks:
   CCNTR.........Generate a contour plot file from an image with CC or MF
                 plotted.
   CNTR..........Generate a contour plot file or TV plot from an image.
   GREYS.........Plots images as contours over multi-level grey.
   KNTR..........Make a contour/grey plot file from an image w multiple
                 panels.
   MFPRT.........Prints MF tables in a format needed by modelling
                 software.  In 'STAR' mode, scale source size by flux
                 divided by CLEV.
   PCNTR.........Generate plot file with contours plus polarization
                 vectors.
