Re: [Ifeffit] question about Eo and simultaneous fitting

      Hi Shelly,

Interesting--I've never tried that method with samples that I expect
to differ in oxidation state. If it's differing in oxidation state,
the local environment is probably different too...particularly,
nearest-neighbor distances should be changed significantly. So how do
you align the chi(k) data with each other, when they oscillate at a
different frequency?

The approach that I like to take, is to vary the choice of E0 in the
background subtraction step so that the chi(k) spectra are well aligned
with each other and the theory.  Then only one Ezero parameter is
needed.
Cheers,
Shelly
