“observable” in the VL2 simulation are ascribed red filled symbols. Filled black circles are satellites that have lost $\ge$90% of their mass since infall, but do not satisfy the destruction criteria previously described: stripped of their stars, they actually appear much fainter than the “observable” ones (see P10, B13). Dark objects are marked by empty circles: simple empty circles have a mass smaller than the minimum to retain baryon and form stars, while objects crossed in addition with an “x”, represent subhaloes that do not survive to the baryonic effects (e.g., baryonic disc, etc).

Note that the Z12 correction was not applied to satellites with $v_{max}>{\rm 50km/s}$ (for example, satellites with $M_{V}<-16$, the 5 most massive satellites at infall of VL2). In fact, those subhalos are Magellanic-like and gas-rich at accretion, possibly including an additional effect of adiabatic contraction that is not accounted for in the correction. The model also assumes small subhalo mass compared to the host. Therefore Magellanic-types are considered of a different dynamical nature and excluded from the model, as in, e.g. Simon & Geha (2007).

We obtain 3 satellites with $v_{1kpc}>20$ km/s, in agreement with B13. However, our central velocities are smaller: the correction to the
