[Ifeffit] Can the degeneracy (N) in Artemis be a variable?

[Bruce Ravel]

Peng's question is so common on our mailing list that I would like to
write a section of the Artemis document addressing it.

At heart, there are two issues.  The more important is that N is very
highly correlated with S02 (and other things!).  The operational issue
is the choice I made about only allowing numbers in the N box in
Artemis.

I would like some suggestions for literature references on the more
important part of this question.  Specifically, I'd like to know what
references all of you cite on the topics of this high correlation and
of solving the problem for real measurements.

With this bounty, I'll write up a section of the document which we can
use when this question comes up in the future.

Thanks,
B
