I am trying to configure the instrument in Profex but I can't get a chi-squared value below 9.65 for LaB6. This is the configuration of the equipment, which is a Bruker D8 Advance with a Linxeye detector:
Can someone tell me the correct way to configure it?

Thanks, Markus for your help.
I have uploaded a document with screenshots of the refinement with some magnifications in some areas so you can see the profile of the peaks. Also, I have set the SRT that I am using to refine the profile.
Finally, the LaB6 is a NIST660C.
