Hi Terry, The only possible difference would be due to differences in background subtraction. In practice, it’s a good idea to collect data ~1 inverse angstrom above the range you will analyze to make sure the background behaves properly toward the top of the fitted range. But beyond that it

Hello, I am a bit confused about the range of k-space, which may affect the quality of EXAFS fitting. I would like to understand whether there is a difference between the fitting using an identical fitting range of k-space obtained from different range of k-space collected. For example, is
