a, b Diffuse intensity calculated for the projection maps in Fig. 2a, b, respectively. In both panels, insets show a magnified view of the diffuse intensity around the [10] and [11] Bragg peaks (indices are in 2D). The circle in the inset in a illustrates the size of the mask used in the Fourier filtering to yield the displacements shown in Fig. 2b. c, d [11] and [1–1] components, respectively, of the displacements in Fig. 2b. In each panel, the two colors highlight the positive and negative displacement directions. e Overlay of (c, d). f Grayscale rendering of Fig. 2b included here to facilitate the side-by-side comparison with (e). The vector sum of the two components in e can be seen reproducing the total displacement in (f).
