Dear Elsa, It sounds like you want to adjust the data chi(k) so that deltaE0 is 0 in a fit. Is that correct, or are you trying to do something else (say, align the XANES)? If that assumption is correct, you want to change the E0 used to extract chi(k) from the experimental spectra -- the E0 of the background subtraction. That is what sets k for the data.
If that's not clear or not the right question, let us know, --Matt On Mon, Sep 27, 2010 at 2:00 PM, Elsa E.
