Are you fitting the sample to detector distance and the wavelength/unit
cell ?
Having a typo in the wavelength can do this sort of thing. Your legend
suggests someone input an energy of 70 keV. This is not an X-ray
absorption edge, and so surprising if it is exactly true.
Best,

A follow up to my previous question, for people who read this is in
the future. I have (hopefully) attached what my position calibration
appears as after performing the 2D image tilt calibration. It seems
that I am able to fit a function similar to the previous mentioned one
in order to model this shift, on the order of rtrue = rmeasured * (1 +
0.004 (rmeas/detectorhalfsize)^2). This disagrees with the negative
“a” value obtained in the paper, instead yielded a necessary increase
in the diffraction ring diameter. Any help on this issue is still
appreciated.
