Correlation between R₁ and stellar mass for central (left panel) and satellite (right panel) galaxies in the sample. The median values for each bin are plotted together with the 16% and 84% quantiles (shaded area). For bins with fewer than ten galaxies, single values are plotted. Both fits to the data are for stellar masses M_★ > 10^8.5 M_⊙. For comparison, we plot the relation for R₅₀ in purple.
