Ah, right. I see you *were* reading the header documentation.
Sometimes that's the problem. :-)

What you want to do is define the variable "pos" before
you use it in the TVIMAGE command. That will solve
all your problems, I think:

pos = [0.1, 0.1, 0.9, 0.9]
tvimage,bytscl(-hst,min=-20,max=0),/keep_aspect, position=pos
imcontour, alog(sm), hdr, nlevels=3, min_value=-0.6, max_value=3, $
position=pos, /TYPE, /noerase,color=fsc_color('black'), $
subtitle="", title="Test"

Cheers,

David
