An illustrative breakdown of the classification of the scattering functions of spheres with a linear contrast gradient into the three regimes discussed in the main text, where each column corresponds to a unique region. In the top row, the reduced squared radius of gyration [R_{{\rm G}}^{2}/R^{2}] as a function of the contrast ratio ρR/ρ0 is depicted. The location of the respective regions labelled (I), (II) or (III) is indicated by the darker shaded area. The middle and bottom rows display selected form factors P(Q) and measurable structure factors SM(Q) that exemplify each region's variability in the shape observed during contrast variation. 〈R〉 indicates the mean radius of the particles. Note the shared axes of P(Q) and SM(Q) between rows and columns.
