Basic Information on velcolor
Task: velcolor
Purpose: Make an RGB image cube to display velocity as color.
Categories: image analysis
VELCOLOR makes a three-plane, red-green-blue, Miriad image cube
that can be used to generate a colour display of the third axis
of a data cube, typically velocity. The RGB planes must be
superposed in a suitable viewer.
The algorithm weights the channels so that the apparent
intensity of the superposed RGB planes is independent of color.
For more details see Heiles & Jenkins (1976), A&A, 46, 33.
Key: in
The input image. No default.
Key: region
The region of the input image to be used. The 3rd axis region
determines the range from blue to red. See documentation on
region for help of how to specify this. Only the bounding box
is supported.
Key: pivot
Center channel of input image for output green image.
Default is 0.4*trc+0.6*blc
Key: out
The output RGB cube. No default.
Key: clip
Two values. Exclude pixels with values in the range clip(1) to
clip(2). If only one value is given, then exclude -abs(clip) to
+abs(clip).
