Hi, I'm working with Athena (00.8.046 version). I have two questions about xanes treatment : 1- When I open a file as xanes(E) the self absorption correction is not accessible. I must open it as mu(E). Why? 2- About Peak fit, It's possible to introduce new functions? Thank you very much. L. Khouchaf Analyse Physique Centre de Recherche de l'Ecole des Mines de Douai.

That's an easy question! That would be a bug. I'll fix that in the next release.

Depends on what you are asking. If you want to define an arbitrary function at the level of using the peak fitting dialog -- that would be a lot of work to implement. If you are asking for a specific function, let me know what it is, and I'll consider adding it in the next release.

I asked for specific functions to fit the resonance present in xanes spectra of
some compound such as quartz SiO2. I will show to you some example in next
workshop at SLS.
Thank you.

Improving the peak fitting dialog in Athena is on my list of things to do: http://cars9.uchicago.edu/iffwiki/HoraeToDoList I look forward to seeing you later in the month at the SLS and look forward to your suggestions for how to make the peak fitting better and more useful.
