[phenixbb] anomalous signal

I was wondering if the f'' determined by XANES experiment is 
quantitatively significant and if it can be contributed by two different 
anomalous scatterers.

For example in my protein I know that Co and Zn are present. In theory, 
at Zn absorption edge, I have a contribution from Co too. If I perform a 
XANES experiment to determine Zn absorption edge and I obtain a f'' of 
5.87, does this value correspond to only Zn signal or to a sum of Zn+Co?

Thanks a lot
