I got some neutron diffraction data which possesses asymmetry peaks. Normally
I use Pawley refinement only changing sigm 2 gamm 2 gamm 1 for peak shape but
it does not take asymmetry contribution into refinement. I wonder if I could
vary some other parameters in ccl file such as taus and tauf which are fixed as
instrument parameters in conventional measurements.
With best wishes!
