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 fitted using different models.
Comparing data and refinement results might help answering such "intimate"
questions like:
- How good is the program I use (or going to use)?
- What kind of model and parameters are the best for this or that setup and
sample?
- Is my instrument efficient enough and well aligned?
- Whether the instrument I plan buying or the beamline I think visiting is that
good as the advertisement suggests?
......
So, the benefits are evident and the "only" problem is to find a coordinator of
the movement - is it you, Simon? ;-)
Regards,
Leonid
