It is possible with the Peak Fit menu item however, you might wish to try xraylarch instead as it has a lot of useful tools for peak fitting of this kind.

Dear, all,

I am a new XAS user. I have done preprocessing of my data in Athena and have been trying to export the XANES data as a .csv file. I would like to fit the pre-peak region to pseudo-Voigt line shapes to extract approximate relative intensities of various transitions (A1, A2, A3, and B).  Attached is a screenshot from an article for your reference (https://doi.org/10.1021/jp981644k). 

Is it possible to do so in Athena?

Any help would be appreciated.

Kind regards,

Kumar
