Figure 8
The error according to equation (4)

between the modelled intensity and all measured projections (= 240) as a function of the number of projections used in the optimization. The two curves show the error metric for data sets where the projections are reduced by keeping constant either $[\Delta\alpha]$ (blue) or $[\Delta\beta]$ (black). The spherical insets show the angular sampling schematically drawn on a sphere, where each object orientation (α, β) can be represented by a point on the hemisphere.
