Correlations between the residuals in the M_• − σ and R_e − σ (left), and M _⋆  − σ (right) relations at each σ (Hopkins et al. 2007b), for the full sample of 57 galaxies (a–b), and for a more consistent sample (see text) of 52 galaxies (b–c). The corresponding intrinsic scatter and Pearson linear coefficient are reported in the upper-left corner of each plot. The symbols are the same as in Fig. 1. Galaxies inside the black circles are pseudo-bulges.
