Pericenter vs. apocenter properties of the galaxies in the sample with 3D velocity errors < 100 km s⁻¹, as indicated by the labels. The top panel plot shows the results for a MW DM halo of virial mass equal to 1.6 × 10¹² M_⊙, and the lower panel for 0.8 × 10¹² M_⊙. We also show typical virial radii in both plots. Gru I is omitted in the lower plot because of the very large apocenter.
