[Ifeffit] Multiple scattering paths in fitting

Hi all, I just read the discussion on "sigma^2 values for multiple scattering paths ". One thing is clear that inclusion of multiple scattering path may increase the quality of fit. I have also some questions related to MS paths. 1. What else information can be obtained from multiple scattering paths? 2. What values of delr should be relevant for MS paths. 3. How can we determine the bond-angles from multiple-sacttering paths using Artemis fitting method. With thanks Abhijeet Gaur School of Studies in Physics Vikram University, Ujjain.
