Figure 2.

(a) Computed center of mass map of sample rotation in $\varphi$ of a selected slice through the thickness, with colors defined by the colormap to the right. A full movie showing the $\varphi -\chi$ mosaicity map over 40 $\mathrm{\mu }$m in z direction with 2 $\mathrm{\mu }$m steps is presented in Supp. Mat. (b) Weak-beam contrast of the same slice showing dislocation boundaries as the pink dotted lines, like the one circled in yellow, for clarity. (c) The intensity profile of the dashed-line trace in (b), showing peaks that describe the positions of each dislocation in the boundary (B1 in Fig. 4). The figure is made using the MATLAB code in the link https://github.com/leoradm/Dislocation3DAnalysis.git.
