Caption: Figure 4.

The distribution of MW satellites in size magnitude space. GCs are shown as squares, DGs are shown as circles, and Lae 2/Tri II is represented by the large star symbol. The color scale indicates the ellipticity of the various satellites. Lae 2/Tri II’s ellipticity and half-mass–radius show very similar values to those of the four satellites: Seg1, Seg2, BoöII, and Wil1. Finally, we also indicate the recently discovered MW satellite, Laevens 1/Crater, given by the large triangle. The data for the GCs were taken from Harris (2010) and the DGs from McConnachie (2012).
