Figure 3
Results of angular-correlation analysis. The number of Bragg spot pairs are shown as functions of cos ψ. Blue lines depict the experimental angular correlations of (a) {101}_hcp − {101}_hcp, (b) {111}_fcc − {111}_fcc and (c) {101}_hcp − {111}_fcc. Green dashed lines depict the peak positions of the angular correlations calculated by evaluating cos ψ for the two corresponding reciprocal lattice vectors (see Appendix A

). Numerical simulations were performed to account for the peak broadening in (a) and (c) (red lines). The details of the simulation are provided in the main text. The optimized parameters in the simulation are σ_xy = 0.02 Å⁻¹ and σ_z = 0.25 Å⁻¹.
