The local rotation of the crystal lattice can either be directly mapped onto the crystal struc-ture (Fig. ), or visualized in the form of a pole figure, where the direction and magnitude of the tilt are calculated in polar coordinates (Fig. ). Each point on the pole figure represents an identically colored pixel from the image in Figure . The color varies continuously from one end of the crystallite to the other, indicating that there are no sharp discontinuities at the length scale of 100 nm. This pattern is characteristic of a crystal 'bending' in one direction perpendicular to the c-axis. While no striped features are visible in the tilt map, the bending is orthogonal to the direction of the stripes observed in the strain map.
