2D gaussian

Hi all
Is there any body know about value of correlation (cor) which appears in 2D Gaussion equation in curve fitting?
Best regards
You can read a little bit about it here:

DisplayHelpTopic "Notes on the Built-in Fit Functions"

Execute that command on Igor's command line, then scroll down (quite a ways) to find the topic about Gauss2D.

If you have further questions, it would help if you could be more specific.
