Extracts from the laboratory X-ray diffraction ( \lambda_{\mathrm{K} \alpha 1}=1.5406 \AA and \lambda_{\mathrm{K} \alpha 2}=1.5444 \AA) pattern projections for (a) \mathrm{CaPr}_{2} \mathrm{CuTi}_{2} \mathrm{O}_{9}, (b) \mathrm{CaNd}_{2} \mathrm{CuTi}_{2} \mathrm{O}_{9} and (c) \mathrm{CaSm}_{2} \mathrm{CuTi}_{2} \mathrm{O}_{9} from 800 to 1460 K, showing the evolution of the (111) primitive reflection and (221) cubic reflection as a function of temperature.
