Pericentric distance compared to the projected semi-major axis half light radius for the sample of likely MW satellite galaxies (excluding the highly likely long-term LMC satellites of the LMC in Table 2) with error in 3D velocity less than 70 km s⁻¹. The filled and open squares show the results for the “Light” and “Heavy” isolated MW potentials and the asterisks for perturbed potential. The arrows indicate those cases where either the median or the 84th percentiles were undefined. We only consider cases where the galaxy has already experienced a pericentric passage.
