Figure shows the SXDM results from imaging a single NMC particle. While any reflection can be measured, the 003 peak was selected because it corresponds to the spacing between layers of the transition metal slabs (Fig. ), and is therefore quite sensitive to heterogeneities in the NMC structure. The diffracted intensity map (Fig. ) is used to mask the image, so that only pixels where NMC is detected are fit. The d-spacing map of the particle is shown in Figure . It is often more visually instructive to plot the d-spacing maps as differences from the mean value for the whole crystal, which allows areas of relative compressive and tensile strain to be easily detected (Fig. ). The histogram of the d-spacings is shown in Fig- , which represents the peak shape and width which would be observed using powder diffraction, considering only the one particle.
