Thanks David,
I finally got the polyfillv to work (after converting my data to
device coordinates) but it won't plot because of memory (unable to
allocate memory to make array). I imagine this may be related to the
fact that the !d.x_size is 17780. Am I wrong in thinking this? I
generally see the device size as being 512.
And I am new to IDLanROI so I have been reading through
http://www.physics.nyu.edu/grierlab/idl_html_help/objects_an 3.html
and am still at a loss as to how I can convert the contour plot into a
ROI and fit an ellipse to it... any links to tutorial pages would be
stellar! I think I am at a similar stage of confusion as this one guy
whose post I found and paste below:
