[Ifeffit] Cu oxide fitting result

Hi all, I am fitting Cu2O data using Artemis. I got a very good fit. But there are problems with the parameters. 1) The value of SO2 is coming very low 2) The value of sigma*2 for different path is coming very different from each other. 3) I have used a number of paths for the fitting as one shell has contribution from many paths. Also the paths are very close to each other (i.e. Reff), So how I should report the fitting results. I am not able to understand these results and also that where I had done mistakes, so please tell me. The Artemis project file is attached herewith
