Hi Mauro,
I would like your opinion on the procedure to convert the experimental mu_exp(E) in arbitrary units (counts) to mu(E) in cm^-1.
Does it already exist a software that makes this work automatically? Could be interesting to implement it in Athena?
Here is our approach for normalization: mu_th = S*mu_exp + Bkg where S is the scaling factor and Bkg is the background function (both pre- and post-edge). In addition to polynomials, an erfc() are used to account for the scattering leaking into the fluorescence window. This normalization scheme gives us fairly good results for a series of data with changes one XANES. If you like, I can send you my codes (in MATLAB) and the manuscript (written 3 years ago for JSR, but got frozen on someone's desk). Tsu-Chien <Chien>001000</Chien>
