[Ifeffit] difference between Zn-Zn/Fe and Zn-Fe paths

[Hashem Stietiya]

Dear All,

 

Is there a difference between fitting a second shell with two separate paths
(Zn-Zn path and a Zn-Fe path) each with its own parameters and fitting that
second shell with a combination of two paths (Zn-Zn/Fe)? When would I choose
to do that latter, and how? 

 

I hope I made myself clear!

 

Thanks,
