68.3% (darker regions, blue in the online version), 95.4% (magenta) and 99.7% (lighter regions, cyan) confidence areas in the log C − log M_h/h^-1 plane and in the M_∗ − M_h/h^-1 plane when the probability of the dynamical fit is combined with the probability of the stellar mass surface density and of the C − M_h distribution from simulations of structure formation in a ΛCDM cosmology. The mass distribution is that given by the BVIgi map for the areas shown in a) and b), and by the BVI map for the areas in c) and d).
