Figure 3
Plots of measured (blue) and best-fit (red) PDFs of CaTiO3 with the difference curve plotted in green offset below over the r range 1.6–50 Å. The model for the best-fit PDF is from (a) the constrained Glazer tilt model in Glazer system 10 and (b) allowing all the structural degrees of freedom of the Pnma space-group model.
