Dear IFEFFIT members, Thanks for all your suggestions, we got the idea to revise our manuscript without just comparing the CNs. We are also planning to provide more discussion for the selection of S02 and factors thay may affect it. Thanks for your in depth discussion. On Sun, Oct 3, 2021 at

Hi everyone I wonder how much effect on the expt value of S02 comes from background subtraction including previous edges, the energy dependence of the atomic background, and the range of the EXAFS. Theoretically S02 is nut a constant but a spectral average. I’d like to see a careful study with a

I think that the variability of S02 between different samples, detection methods etc. may or may not be a big concern for you if 1) the error bars in the CNs (that you are not reporting) are larger than the difference in their mean values (that you are reporting), and/or 2) larger than the

Since S02 is a parameter in the description of EXAFS and not of the experiment, it's independent of technique. Overabsorption (misnamed 'self-absorption') can reduce the *measured* amplitude, an effect which can be fudged in analysis by reducing S02. If the sample is truly homogeneous (on

Dear IFEFFIT members, I am sorry to bother you again. I asked about S02 selection for the first major revision. I just received the second revision. The reviewer is not satisfied with one S02 value for all our samples. " 1. I am still not satisfied with selected SO2 value (it is set to 0.85).
