Well, you are right, your first problem is a 2D
histogram problem. :-)

Your second problem is more worrisome. (And it is
JD Smith's routine, not mine. I just host it.) This
may truly be one of those problems that don't have
a good solution. Or, maybe I just haven't thought of
it yet.

If I just wanted to get on with my day, I'd probably
delete product.pro from the NASA library. It seems to
be a subset of the IDL routine, although there is no
question in my mind which was on the IDL scene first.

But I can absolutely see why this isn't a good long-term
solution. Maybe PRODUCT has been in IDL long enough now
that Wayne could safely remove it from the NASA Library.
I don't know. I'd like to hear what the principles
have to say about this.

Cheers,

David
