Hello Neil,
I guess you might have tried this already - do you have any signatures in the I0 data? Such as a glitch or any other edge absorption. Sometimes these can be used as “internal calibration”.

Generally, I am not at APS to help them collect spectra, I help analyze the data afterwards. A user came to me recently with some Ce L3 data that does not have reference foil data. If I am trying to compare the EXAFS of several different samples (all which should be similar oxidation state, and of which I have other references of similar oxidation state). Does anyone have a suggestion how to work up the data if I can’t calibrate it?
