FWIW, my RedHat 6.1 system cannot plot this file using either ictrans or
idt. Ctrans *does* work if I left click in the ctrans window once
(something I would not ordinarily have to do in order to see the
picture). So there is definitely some sort of problem here. Locating
and identifying the precise problem may take some doing, and in the
final analysis may depend on your point of view. I'd be keen to hear
how this is resolved.
