Fig. 2

a, b, e, f The stereographic projection of local polar displacement vector with respect to [001]c. The right color bars represent the density of polar displacement vectors. c, g the magnitude and d, h the angle histograms of local polar displacement vectors. θ indicates the angle of each displacement vector away from the direction of average polar displacement vector <D>.
