Yes, I agree. The "problem" you seem to describe has to do with
how the program finds the "contour". In my experience, there are
*hundreds* of ways to do this, all of them correct (or incorrect,
I guess, as you please). But, in any case, not much you can do
if you choose to work with IDL. Although you might try ISOCONTOUR.
That uses yet another algorithm, I think.

Cheers,

David
