Hi Ilya,
I apologize in advance if this sounds stupid.. could you please explain me
why it is obvious that your data needs to be rebinned?
thank you

Hi all,
I have a question regarding the chi(k) function isolation and rebinning processes. I have some data recorded in “quasi channel-cut” modus, i.e. with the mono constantly moving and the data points collected with the highest possible rate. With 180 sec measurement in yields to a spectrum of ca. 8600 point, which obviously needs to be rebinned. The rebinned data, however, does not look good in k-space even if multiple data are merged. Moreover, I have an impression that the raw spectrum in k-space does not have those 8000+ points anymore but significantly less. Is there any reduction of the data points number that is not seen (e.g. as a preparation step for FT)? Since the unbinned data has higher quality, does it then make more sense to keep using it for EXAFS analysis?
Thank you
Ilya Sinev
