2D correlation maps C(q, Δ) calculated for (a) the simulated scattered intensities in 3D reciprocal space and (b)–(e) 2D diffraction patterns from a randomly oriented sample averaged over (b) 5 × 104 and (c) 5 × 102 patterns. The scattered intensity distribution in 3D reciprocal space and the 2D diffraction patterns were simulated for the same colloidal crystal with an f.c.c. structure. (d) Pearson correlation coefficient r(N) between the CCF maps averaged over different numbers of 2D diffraction patterns and the CCF map calculated for the intensity distribution in 3D reciprocal space for the same sample. (e)–(f) 2D correlation maps C(q, Δ) calculated for 2D diffraction patterns obtained by rotation of the sample with an f.c.c. structure around the (e) [111]f.c.c. and (f) [110]f.c.c. axes.
