| + | Then you can do a normal Rietveld refinement in MAUD to obtain the exact instrument parameters. When you are done save the whole analysis as a file. There is also a way to save the instrument parameters separately but this sometimes doesn't work. The safest way to load the instrument parameters in the future is to load the whole analysis and change the phase and the sample. In a future analysis you don't refine the instrument parameters anymore. | ||

| To do this, you should first have a look at your calibration image with Fabian. Check the intensities of the rings and the background (values at the bottom right of the Fabian window). Estimate a threshold value which clearly separates the background from the ring intensities. | To do this, you should first have a look at your calibration image with Fabian.
