Figure 6.

Computed COM maps of $\varphi$ rotation (i.e. rocking curve COM map) (a) and relative axial strain (b) of (002) reflection. The color key shows the $\varphi -2\theta$ angular distribution in the scanned range around the local intensity maxima for the respective axes (c). These maps show the projections from a volume illuminated by box-shaped beam having a size of $400\times 400\mathrm{\mu }{m}^2$, rather than a line focused beam (See Supp. Mat. for more details). The measured strain is rather homogeneous having values below ${10}^{-4}$, in spite of the clear boundaries that are visible in the $\varphi$ COM map. The figure is made using the MATLAB code in the link https://github.com/leoradm/Dislocation3DAnalysis.git and https://gitlab.esrf.fr/julia.garriga/darfix.
