[Ifeffit] Emission spectra of Cobalt

Hi Timna,
The energy arguments for the XES in FEFF84 are energies of the valence
electron relative to vacuum, so emin should be a negative number.
Try
XES -20 0 0.3
This should capture at least some of the XES. You can play with emin to get
the range right. Note that the number of energy points in FEFF84 is fixed,
and if you specify a small energy step (the third parameter) you will not
achieve the full range that you specify.
Cheers,
Josh Kas
