Polynomial angle intensity
Sometimes, intensity calibration will not work out the box. I never really understood why, but know a way to fix it...
If you can not reproduce variation of the peak intensities with 2 theta in your calibration, you should first check that the crystallographic properties you enterred are correct. If they are, and if you can still not get the right intensity ratios between peaks, you can use the
In order to activate this mode, open up your instrument parameters tab, and select
Those parameters will calibrate the intensity of the diffraction as you move away from the beam center.
Refining parameters for the "Polynomial angle intensity" model
In order to refine those parameters, I typically run a refinement with
and it converges very quickly.
