Dear Simon,
I think it would be nice to have an open web-resource summarizing good practice
of full-profile refinement, especially if it is supported by real diffraction
data for, say, simple widely available standards (quartz, silicon, corundum
etc.) measured at various diffractometers and fi
Dear All:
Indeed, despite some more advanced approaches to modeling diffraction line
shapes, the good, old Cagliotti function is still in use probably for
historical reasons (as it is the case with many other things in sciences).
However, to be fair to (practically all major) Rietveld programs, th
