[Ifeffit] Peakfit tool - determination of width

[Gudrun Lisa Bovenkamp]

Hey Bruce,

I was wondering how the width in the peak fitting tool of Athena is
connected to the real data. What I mean is:
A gaussian peak with a width of 1 (eV ?) seems to have a FWHM of 2 eV.

Is it possible that you mean with "the Gaussians (...) are unit 
normlized (...)"
the width is actually "sigma" and the amplitude is actually "mu" in 
the
pure formula?

Thanks,
Lisa
