D3 nanodomain component in real space consists of octahedra that exhibit short-range anti-phase ordering of b-axis tilts along b and long-range ordering of b-axis tilts along a and c denoted as {a}^{0}{b}{LSL}^{---}{a}^{0}. Short-range and long-range correlation lengths are equivalent to out-of-plane and in-plane correlation lengths, respectively, in Fig. 1. Each octahedron is represented by a sphere, where the colour represents the octahedron tilt angle along the c (a), a (b) and b (c) crystallographic directions. Colours represent positive/negative tilts, whereas white corresponds to a random (close-to-zero) tilt angle.
