Hi Scott et al.,
Thanks for bringing up this issue. Whether or not McMaster corrections
are useful does seem to depend on details of the measurement. But
my question is: for the cases where they are useful, can one do
better? As the data & theory get better and better, perhaps we should try
to
Thanks, all!
Here's what I got out of the discussion:
FEFF is calculating the "correct" chi(k), and applying an approximate
correction introduces additional sources of error. But the only way to
measure chi(k) is to extract it from unnormalized data, and the
original definition of chi was
I apologize if I have abused the list while working on my text. I will
find a different channel for raising these questions and requests once
the current discussion is complete.

HI Scott,
I don't think it's abusing the list to bring up topics of discussion.
I was just noticing that I was finding myself being more reserved in
my answer than if someone had simply asked "what's the McMaster
correction and when do I need it"?.I haven't looked at your book
chapters partly
Dear EXAFS experts,
I am quite a beginner, and that's might be an ignorant question but really
important to my work, so I would be happy to get a direction:
what would be the right way to weigh in the effect of temperature in soils

Hi Hana:
I would add that you should expect your sigma2 values to be smaller or the
same since you collected data at 10K in comparison to those collected at
room temperature. If the origin of the disorder is thermal then your sigma2
values will be a smaller than the RT ones. If the orgin of the
Dear users,
I would like to quantify the single scattering (SS) and multiple
scattering (MS) contributions to the EXAFS spectra over a range of k
values. I adopted the following approach and I would like ask
experienced users if my approach is sound:
(1) Run a regular EXAFS (default NLEG=8); I as
