Folks,

Someone asked me this weekend how to fit a Gaussian
to the output of the Coyote Library routine Histoplot.
Good question.

I was surprised to learn (well, "shocked" might be a better
word) that the author of Histoplot had already anticipated
the need for this functionality, and had provided the
appropriate output keywords to make this possible.

Here is how it can be done:

Cheers,

David

P.S. Let's just say it's not *always* IDL that surprises you! :-)
