Hello,
I would get a copy of Liam Gumley's IMDISP or Craig Markwardt's
PLOTIMAGE, each of which will show the image. Then use the OVERPLOT
keyword to CONTOUR to simply overlay you contour data.
The liks below are from a post earlier this week.
P.S. O/PLOTIMAGE can be found at:
http://cow.physics.wisc.edu/~craigm/idl/idl.html (under graphics)
and IMDISP is by Liam Gumley and available at:
