This is awesome - I've got it up an running now. Just to note, I had to delete the non-functional plugins from my AstroImageJ directory before it worked.

And you're right, the function is very sensitive to the parameters you pass to it. At low smoothing radius (less then 2, as you indicated), the function stalls AIJ. In addition if you use line integration steps that are too large (above around 0.05 for this image) you get "kinks" in the contours. Also, I'm not entirely sure I understand how the last two parameters ("Distance between lines" and "Stop line....") interact with each other.

But in any case, I am very thankful for your quick work here, and this might even be enough for what we need to do.
