[Ifeffit] Fitting Cu2O

[abhijeet gaur]

Hi all,
         I am fitting Cu2O data. But when I fit the first shell using the
first path, I got the guess value for SS parameter negative which is around
-0.0028 and also the guessed value for SO2 parameter comes out to be around
0.52. Are these values logically correct as I am getting a nice fit.
      Also when I use the same SS parameter but with positive sign for the
first shell i.e., 0.0028, the guessed value for SO2 parameter comes out to
be 0.61.
     When I fit the higher shells by using the same SO2 and Enot value for
other paths, the value of SS parameter for these paths is coming very high ,
i.e., 0.016 - 0.021. But the fit seems to be quiet good. Are these higher
values of SS parameter correct. The resulting figure is attached.

with thanks
