Same as Fig. 6 for C- and S-types with a modified scaling law (“idea 2”). After this modification, both synthetic SFDs agree very well with the observed SFDs above the observational limits, and almost none “undershoots” the observed SFDs below the limits. The respective pseudo χ² was 50.0. For reference, we also plot the corresponding best-fit scaling laws for the C- and S-types (Eqs. (3) and (4)) with the gray areas corresponding to the range of sizes below the observational limits.
