I object the use of "hosannas of adoration". Other than the use of Greek mythology, I propose the mailing list to be religion-neutral and tautology-free. How about "you should consider praise or adoration", instead of "you should consider hosannas of gratitude".

While I defend that principle as a very important one, I'm not claiming it applies in Matt's case--it probably doesn't. To reproduce features at high-R, it IS necessary to have a model (i.e. paths) that cover the high-R contribution, and it sounds like Matt does not have those paths included in his model. But it's not necessary to FIT up to high R.
It doesn't apply. Matt filtered his data. Matt used paths that only include Fourier components within the filtered band. To suggest that it may somehow be reasonable that the fit could turn out other than how it did runs a real risk of misleading this fellow who is, apparently, a newcomer to EXAFS analysis.
P.S. My least favorite warning that Artemis provides is the one that tells you that you're including paths outside the fitting region, for just this reason. It's easy enough to change the preferences so that Artemis doesn't give that warning, and it's usually one of the first things I have my students do when they're first learning to fit.
OK. Whatever. Instead of complaining about this, perhaps you should consider hosannas of gratitude that I make it possible, easy even, to accommodate preferences different from my own.
