I suspect the answers from the many times this question has been asked before
will be helpful to you. For example, this post from Scott --
in response to a thread on this very topic -- is quite helpful.
If it's still not clear, then ask again about the part that remains confusing

Subject: [Ifeffit] The degeneracy and the coordination number
I am confused about the degeneracy and the coordination number used in the
I want to get the coordination number of 1st shell of my copper sample, so I
set a guess number N1=12(initial guess) as the coordination number which will
vary during the fitting iteration, but when I am looking at the 1st path's
parameters, there is another N appear which may stand for the degeneracy.The
1st path of copper model is single scattering, so the degeneracy N equals
coordination number . But when I set N=12, the guessed N1 will have a value
which is closed to 1, only when I set N=1, the guessed N1 will have a value
which is closed to 12. It seems that N and N1 are reciprocals. But I think N
actually equals N1 in the single scattering case.
So I am really confused, If I want to get coordination number of a shell in a
fitting, how can I deal with floated coordination number and its path
Thanks so much.
