Absolute V-band magnitude M_V, half-light radius r_h, and pericenter radius r_p for GALACTICUS analogs of Segue 1, Tri II, and Tuc V. The left-hand panel shows the distribution of M_V for analogs selected by r_h and r_p; the middle panel shows the distribution of r_h for analogs selected by M_V and r_p; and the right-hand panel shows the distribution of r_p for analogs selected by M_V and r_h. For comparison, the dotted curves show the uncertainty distributions of the observationally inferred values (which can exhibit minor discontinuity due to how we model asymmetric uncertainties).
