Dear Enyuan, in my experience, peak fitting works very well with Athena. Try not to fit only the prepeak, but maybe include an arctan describing the edge (see attached pdf, the fit was made using athena). This makes isolating the prepeak much more reliable.

Dear all,
I was wondering if anyone could comment on how to get the centroid of pre-edge by fitting the pre-edge peak by pseudo-Voigt functions. I tried to do that in Athena, but it seemed that peaking fitting part is the relatively less developed function in the software. Any comment would be appreciated.
