Hi Daria: I smooth (or boxcar average) the data which it is oversampled, such as in a continuous scan where the data in the exafs region is spaced closer than the usual delta k of 0.05. I generally don't like to smooth XANES data since smoothing does tend to attenuate sharp features such as the ones which exist near the absorption edge.

Hello,
In what case smoothing of the data is OK? My data have a lot of noise and smoothing really helps (visually). I compared fit done in Artemis for smoothed and non-smoothed data sets and the result is very similar, however when I searched about it online, it looks like it is not recommended. What is a good way to justify it?
Thank you!
