Manceau also describes his arc-tangent function in his earlier work
(Mn is also my focus):
Manceau, A.; Gorshkov, A. I.; Drits, V. A., Am. Mineral. 1992, 77
(11), 1133-1143.
I've found Farges to be a little vague on how he extracts the pre-edge
features for fitting.

Hello all,
I have done pre-edge fitting of Ti in multiferroic ceramics with Athena. I
have selected error function for the "background" and alternatively
Lorenztian or Gaussian function for *several* peaks, and Athena has worked
quite well. The point is to do it with some systematic procedure, and
You might also consider the method given in:
Manceau, A., Marcus, M. A., Grangeon, S. (2012) "Determination of Mn valence states
in mixed-valent magnanates by XANES spectroscopy", American Mineralogist 97,816-827
(not that I'm plugging my own work or anything :-) )

Hi Dominik,
Thank you so much for your quick response. Indeed, it's really nice fitting
according to your result. But my situation seems a little bit different as
I'm dealing with the Mn XANES data and there're doublets and sometimes
triplets in the pre-edge. Actually, I might as well explain my i
