Description

Colorize any numeric array based on either a linear or non linear scale. Standard XV and TES scales are included but are hard linked to /themis/lib/dav_lib/. The files are included for download below if you require them. You must then edit the code to check for the right directory.

Arguments and Return Values

Input: Any numeric array

Output: A numeric array of contours of the same dimensions as the input with contours of a multiplicative of the interval value

Usage

Syntax: colorize(data [, ignore = VAL] [, type = VAL] [, colors = VAL] [, values = VAL] )

  data   - Any numerical array.
  ignore - null value of the data (Default = -32768)
  type   - apply colorize in "rgb" or "hsv" space (Default = "rgb")
  colors - number of colors to use 1 = 6 colors, 2 =  7 colors 
           3 = XV color scale, 4 = TES colormap, 5 = TES daily colormap  6 = MOLA Colorbar 7 = Blue/White/Red (Default = 1).
  values - values of the data for each color (Assigned linearly by default)
