Dear all,
I am very new with GSAS and some confusions arrised to me during
refinement. I will be very much grateful if anyone helps me by giving the
explanations of the following facts..
1. what the parameter POLA stands for(is it polarization
factor??)? is it necessary to refine POLA when we are refining the XRD patterns
taken by a Brag-Brenteno diffractometer with fixed source?
2. Does 'shft' and 'trns' means sample shift and sample
transperancy? what is the difference when we are refining 'zero' in place of
refining 'shft' and 'trns'?
3. what physical explanation is behind the asymmetry(refined by
'asym') in the peak shape?
