Effect of informative priors on enclosed mass within 5 R_e. The black dots and triangles show galaxies flagged as Good and Good w. rot., respectively, as defined in Sect. 2.2. The measurements for these galaxies are robust. The open red diamonds and blue squares are galaxies flagged as Subpop. and Pecul., respectively, and for which the measurements are not robust. The dashed line is a 1–1 line for reference.
