Hi Yang, There are many reasons why you would prefer your first-shell fit to have your fit include high-k data, when feasible. I’ll name one, just to give you the idea: Suppose you have a substance where you have a good estimate of S02 (transferability from a similar substance measured under t

[Ifeffit] EXAFS fitting - noisy data

2021-08-30 Thread Hu, Yang (HIU)
Dear Ifeffit members, I have some fundamental questions regarding noisy data, and I am wondering how to tell whether the data quality worth doing Fourier transformation/EXAFS fitting or not. For example, the attached MnO chi(k) data becomes noisy from 7 Å-1 when it was measured up to 12 Å-
