[Ifeffit] A small query on constricting mean square displacement in multi-edge EXAFS refinement

[Scott Calvin]

Yes.

The only minor adjustment I can think of to that is something called the “McMaster correction,” which adjusts for an oversimplification in the usual EXAFS method of normalization, and thus can be different for the two edges. But that correction is generally quite small, and the difference in it between two edges is even smaller.
