POL3COL
Type: Adverb   (Real)
Use:  Controls whether and how polarization vectors are colored.
      Vectors are colored by their angle with a circular color pattern
      in hue.  If angles are viewed as 0 (north) to 180 (south), the
      value of POL3COL selects the angle assigned to pure red and
      values from eps > 0 to 180 are allowed.  Color increases from
      green to yellow to red to magenta to blue to cyan to green.
Null value:  <= 0 -> no coloring other than dark or bright lines.
Tasks:
   KNTR..........Make a contour/grey plot file from an image w multiple
                 panels.
   PCNTR.........Generate plot file with contours plus polarization
                 vectors.
