Table 1. Bead types used for the coarse-grained X-ray scattering calculations and their elemental formulae.

The sums of the atomic scattering factors at q = 0, corrected with the displaced-solvent model, are shown in the last columns. The form factors of all beads with f(q = 0) 0, marked in bold, were corrected as described in the text.
