Hi Erin,

Hello, I see in many publications the R value reported with a standard deviation. However, when I look at my resulting data from a fit I don't see one listed. I am still new to EXAFS research and so I am wondering where I can get this information. I am assuming I need to calculate it from another parameter I am just not sure which one.
The uncertainties in R are typically in the fit report. But also, we typically refine a "delR" parameter that is R - Reff, where Reff is the distance (half path-lengh) for the scattering path. So, if you don't see an uncertainty reported for R but do see an uncertainty for delR (or whatever parameter name you used), use that. The uncertainty in R will (normally) be the uncertainty in delR. If I'm misunderstanding the question, pleas give more details about what you are doing. --Matt Thanks for your help!
Cheers,
