I know of one very obscure conference proceeding describing what you are looking for. It was written during pre-Artemis times but the method can be used with Artemis, of course. A. I. Frenkel, M. Vairavamurthy, and M. Newville, A study of the coordination environment in aqueous cadmium-thiol complexes by EXAFS spectroscopy: experimental vs. theoretical standards J. Synchrotron Rad., 8 , 669-771 (2001).

For that in Artemis, we give input as crystallographic data. But If we want to use an experimental standard instead of theoretical standard, how that can be done. Is it possible to use experimental standard in Artemis? or we have to use some other method. with thanks Abhijeet Gaur School of Studies in Physics Vikram University, Ujjain (India)
