Dear all,
Could you give me some advice on estimating the intrinsic loss factor (S02)?
I am trying to estimate the S02 value in the curve-fitting analysis for
Zr K-edge EXAFS.
To do this, I did the curve-fitting analysis on the first shell of
Fourier transform of Zr-K EXAFS of Zr-foil by Artemis. However, there
was a marked difference between the amps obtained by the fitting,
depending on the "Fit k-weights" as follows.
kw amp
1 0.8145660 +/- 0.0486470
2 0.9230700 +/- 0.0673820
3 1.0439100 +/- 0.0854950
1,2,3 0.9081570 +/- 0.0722180
Is this a usual thing? I can't find the reasonable explanation why S02
depends on "Fit k-weights".
I attached the Artemis project file.
Thank you in advance for your cooperation.
