The results of simulations for various types of nonuniform distribution of particle orientations. (a), (c) and (e) The SAXS intensities, and (b), (d) and (f) the amplitudes of the FCs $[| \langle C_{ii}^{n} (q_{1}, q_{2}) \rangle_{i} |]$ for n = 2, 4 and 6 at q₂ = 0.25 nm⁻¹. The results for a Gaussian distribution of particle orientations about the y axis (GaussY) with σ_y = 1.0 [panels (a) and (b)] and σ_y = 2.0 [panels (c) and (d)], as well as a Gaussian distribution of orientations about the xz plane (GaussXZ) with σ_xz = 2.0 [panels (e) and (f)], are plotted together with the results for a uniform distribution (Unif) of orientations. The nonuniform distributions of orientations are shown schematically as insets in panels (a), (c) and (e) (see Appendix D
