        I will need to see your inputs to TVRGB to see why it
complains when the 2 images are the same.  The coordinates of an IR
image and a radio image are probably not the same and one or the other
will need to be regridded.  Send me the IMHEADER outputs for the 2
images for me to advise you.  OHGEO is now the preferred way to do
that regridding.
