Yes, the figures are impressive! I wonder what kind of Bayesian insight one 
should have to see that "in Fig. 6. The difference curve demonstrates that 
Bayesian inference method better reproduces the observed diffraction profiles" 
?? 
It seems that the open-access article charge serves as an indulgence for any 
speculation.

I like figure 1 and look forward to seeing the method applied to quantify 
uncertainty by appropriately
modeling the heteroskedasticity and correlation of the error structure in 
something other than silicon.

Probably of interest to several readers here, a new paper on 
methodology:


"Use of Bayesian Inference in Crystallographic Structure Refinement via 
Full Diffraction Profile Analysis"
Chris M. Fancher, Zhen Han, Igor Levin, Katharine Page, Brian J. Reich, 
Ralph C. Smith, Alyson G. Wilson & Jacob L. Jones
