Fraction of galaxies with simple final decomposition models as a function of multi-component r′-band magnitudes. Here ‘simple’ refers to models which only consist of one component, excluding the nucleus. A bin size of 2 mag was used for both samples. The numbers denote the number of galaxies within each bin. The shaded regions denote the 95% confidence interval based on the methodology of Cameron (2011). For reference, M_r′ = −14 ∼ 10^7.5 M_⊙ and M_r′ = −19 ∼ 10^9.7 M_⊙.
