(a) the absolute brightness of the disk () is plotted against the absolute brightness of the bulge (). (a) S0s (filled circles), S0/a+Sa (open circles), Sab-Sbc (crosses), and Sc and later types (squares). Solid, dash-dotted, and dashed lines show linear fits for the S0s, S0/a+Sa, and Sab-Sbc galaxies, respectively. All the correlations are statistically significant. (b) (disk) versus (bulge) for the galaxies in NIRS0S, divided to two galaxy brightness bins in -band. This figure is compiled from two figures originally published by Laurikainen et al. [27, 36].
