data - sepfile
 Data file
data2 - sepfile
 Second data file (optional)
stdout - sepfile
  Datafile to use with Grey
color - sepcolor
  Color file to use with Grey
fg_linear_or_log - integer
  [1]   forground color display mode
fg_clip_linear- real
  [.5] (0.-1., percentage of max value of each snapshot
         above which data will be clipped dfor linear mode
fg_modulate_log- integer
  [10000]  modulate data for log mode, a large integer > 100
bg_min,bg_max - real

fg_nhue - integer
 [18]  number of hues

 [12]  number of lightness regions
fg_min_lightness,fg_max_lightness - real
 [.3,.8]  range of lightness
fg_saturation - real
 [1.]  foreground saturation
bg_nhue - integer
 [20]  number of background hues

 [.3]  bacground saturation


DESCRIPTION

     Composing two components (x and y, e.g., p wave and s wave) as
      the foreground with a velocity model as the background


COMMENTS

 COLOR SCHEME:
      Forground   H: atan2(y,x) (i.e. 360 degree)
                  L: sqrt(x^2+y^2)*clip (range e.g. 0.8-0.3)
                  S: constant (e.g. 1.0)
                  Number of fg colors = fg_nhue * fg_nlightness
      Background  H: blue -> magenta (i.e. slow to fast)
                  L: constant (e.g. 0.3)
                  S: constant (e.g. 0.3)
                  Number of bg colors = bg_nhue
      Total colors = fg_nhue * fg_nlightness + bg_nhue (default 18*12+20=236)
 NOTE: The log mode displays more data using higher lightness colors.
