Dear IFEFFIT users, I have some problems/doubts with quite basic questions concerning xanes processing. In particular the normalization range. Can anyone please look at my project and tell me if my data processing is correct ? The xanes are at the Fe K-edge, of a F(II)-complex, taken at different temperatures. In fact my question concerns the choice of the starting value for the normalization range. I obtain reasonable lines with a starting point from more that 100 eV after E0. Is it correct to start so far from the edge?? should one start just after the broad feature (onset of exafs ? ) ? if I start the post-edge normalization before ..I obtain different results when I compare the different xanes.. thanks for your help, best regards, bahia
