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
When it comes to rebinning and/or averaging, my preferred way is to use
smoothing spline interpolation as implemented by IgorPro from Wavemetrics. With
a little care, smooth curves with no artifacts can be obtained, in particular
with oversampled data. We use it a lot with XPS data, where in
Matt,
From my experience at the ESRF, many users dealing with XAFS data
collected in continuous scan mode (either in angle, energy or time)
apply the following workflow:
1) average many scans with PyMca;
2) import them in Athena;
PyMca does a linear interpolation using the grid of the first
Hi Matt:
I'll send the data I used for the figures directly to you.

HI Ilya, Edmund, Carlo,
Ilya and/or Carlo: can you post some example unbinned data? As it turns
out, I am adding a rebinning feature in the Larch XAS Viewer GUI that
should be ready for a ready-to-try release very soon (for IIT XAFS School
and XAFS2018).
This seems like a good chance to test the
Yes, we measure fast and have taken as many as 2 points. The problem
is not in the shifts that you mention. This is normal and expected. the
problem is specificallly in the rebinning algorithm in Demeter. It seems
to be different than the one in the old Horae package. I have done a t
Dear Carlo,
do you also measure as fast as possible in the sense that for two
consecutive scans the points on the energy axis are not at the same
positions? This is what happens at my beamline. The differences are
typically very small but there are differences and one should not just
add all
Hi Ilya:
We always take data in this mode at APS Sector 10 and I have also find
that the rebinning function is not working satisfactorily at this time. I
find that for the current version of the software it is better to merge
your data and let IFEFFIT interpolate to the dk=0.05 grid that i
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
