From top left to bottom right: The projections on the three directions around 0 0.75 5 above and below the transition. The experimental data are shown by dots, whereas the fitting of two temperatures are shown by dotted lines, as an example of the high-T phase (Tc + 200 K) and of the CDW ground-state phase (Tc − 20 K) peaks. In c*, twinning was considered, with the distance and intensity ratio between the two kept constant. The temperature dependence of 1/ΔQ on the three directions shows the isotropic shape of the diffuse pattern, which develops complete long-range periodic order at the transition temperature.
