Figure 22
Normalized cross-correlation r(i, j; θ) between simulated particle images in Fig. 3[link] and 2D projections generated at varying θ. The 2D projections were generated by keeping the angles ψ and φ equal to those of the simulated particles in Fig. 3[link] [(a) apoferritin and (b, c) tubulin patches] while uniformly sampling the polar angle θ at 0.5° intervals between 0 and π. In all three cases, r(i, j; θ) is sharp around the optimal θ = θ0.
