A simple question. I am have been doing multiple edge fits of different materials for a while in artemis (diana). Now, I would like to analyze a material with inequivalent sites for one of the edges. I understand how to read in the data and have read in the different feff calculations (for each inequivalent site), but what I just want to confirm that artemis/diana/ifeffit will do the "right" thing, namely coherently add the contributions *within* each feff calculation and add the intensities of each feff calculation -- e.g. I don't think there is any interference between the XAFS signal on different crystallographic sites -- or even if there is it is ignorable at least for first neighbor interactions. If there is anyone out there with experience in doing this (or is the right thing done automatically?), drop me (or the list) a line. Thanks a lot!
