Dear Matthew
you can find examples of determination of life-time broadening,
deconvolution of XANES specra, and discussion about limitations due to
noise in several papers, for example:

Hello,
Since I haven't received a response to my previous question, I just wanted
to make sure I asked it clearly. To elaborate, I am attaching a log from
Athena. The log file lists:
Independent points = 27.057617188
If I attempt to reproduce this result using the equation in the
Sorry, the log file is from Artemis, not Athena...

Try it again with dk and dR extending the range.
Perhaps there is a more subtle analysis of the data range, but I doubt
it, since Matt is on record as suggesting that people not place too much
emphasis on the exact value of N-idp, if I recall correctly. You can
scale your chi-square,

Hi George.
It should be 2*(Delta k)*(Delta R), without the +2, but as a floating point
number. That is, it is deliberately conservative. I believe the subtle
difference you see (that is why the value is 27.06 instead of 27.5) must be
due to rounding of the R values on to a discrete grid.
Of course. I do agree with both Jeremy and Bruce.

I suspect the lack of response had more to do with it being a
non-trivial question asked on a Friday afternoon :)

Bruce, Matt, and Jeremy,
Thank you for explaining this. Your responses are much appreciated.

Thanks. While none of these have to do with pre-edge peaks such as are found
in transition-metal oxides, the assumption of constancy of core-hole broadening
does seem to work.

I think experimental answer could be the simplest one. Perhaps there is anyone
on the list who measured low concentrations of low Z absorber in the high Z
host at both edges?
For example, Cu in Ag (if does dissolve in Ag if made by rapid quenching) at Cu
K-edge, and Ag K-edge (or just bulk Ag
