2D correlation maps C(q, Δ) calculated in the q-range from 25 to 115 nm−1 for the simulated scattered intensities in 3D from (a) f.c.c. (b) h.c.p. (c) twinned f.c.c. and (d) r.h.c.p. structures. The CCFs are stacked together along the vertical axis q. The markers in (a)–(c) indicate the peak positions for the corresponding structures calculated from the geometrical model (see Appendix A[link]). Note that in (c) there are only the peaks corresponding to the inter-domain correlations between the twin domains. The intra-domain correlations from each domain also produce peaks corresponding to an f.c.c. structure shown in (a). In (d) the dashed lines indicate the correlations between the Bragg rods. Only correlations within 10l (black lines), 20l (red lines) and 21l (blue lines) Bragg rod families are shown. Correlations between the Bragg rods from different families as well as for higher order families have been omitted for clarity.
