Jenny,

Those look like photo-emission spectroscopy data.  Nothing in the
Ifeffit package is written explicitly for XPS.  That said, Ifeffit is
quite capable of "peak fitting" -- i.e. fitting an arbitrary
combination of line shapes to arbitrary data.  That is exactly what
Athena's peak fitting dialog does:

You might even be able to coerce Athena to do that with XPS data, but
I won't make any promises.

You could certainly write little Ifeffit scripts to do that sort of
peak fitting.
