Dear Bruce

We have used Athena and Artemis software to analyses the EXAFS. When we do the analysis, we used different S²_o for each path for fitting of Cu₂O data. I succeeded to obtain good fitting by this way. Documents related to percent EXAFS analysis have been mentioned S²_o is one value for all paths. What I want to know is our fittings are correct or not. I am looking forward early response.

About 10 years ago we had being using another program made by Tokyo University in Japan. In this program, the refined parameters also included S²_oj and Nj to the each cells

Thanks
