[Ifeffit] Normalization in Athena

I think the issue you're seeing is most likely due to telling athena
to fit the data between E0+199 and E0+200 with a constant.  I'd
recommend expanding that range some to give Athena a chance -- if
there isn't any data between E=E0+199 and E0+200, Athena won't be able
to figure out what the edge step should be.    If you really want the
edge step to be the value of pre-edge subtracted mu(E) at E=E0+200eV,
you'll have to do that by hand.
