Hi Abhijeet: i think you have to start by looking back at your original data. The Chi(k) looks very iffy for a crystalline material such as the kind you are model. Could you send your Athena project with the original data? My suspicion is that the first peak is mostly due to poor background subtraction. Carlo On Sat, 4 Jul 2009, abhijeet gaur wrote:

Hi all, Thanks for the response. I am sorry as I should attach the figure in a viewable format. Anyways now I am attaching a the artemis project file in which I had used a set positive value for the SS parameter of first path. I am not able to understand the reason for negative SS value. Thanks again Abhijeet Gaur
