Some of the observed properties of the Local Group dSphs Fornax, Sculptor, Sextans, and Carina, which are used in the present study.

dSph LV  ⟨  [Fe/H]  ⟩  M/L rt σ
 [106   L  [kpc]   [km   s-1

Fornax 14  −1.17 12 2.08 11.7
Sculptor 1.4  −1.96 158 1.33 9.2
Sextans 0.41  −2.26 19 3.10 7.9
Carina 0.24  −1.86 88 0.58 6.6

Notes. The luminosity comes from Walker et al. (2009b). The mean metallicities were calculated from Battaglia et al. (2011) for Sextans, from Battaglia et al. (2006), Tolstoy et al. (2004), and Helmi et al. (2006), for Fornax, Sculptor, and Carina, respectively, with the new CaT calibration of Starkenburg et al. (2010). The M/L ratios were computed using the masses derived by Walker et al. (2007); Battaglia et al. (2008); Kleyna et al. (2004). The tidal and core radii are taken from Irwin & Hatzidimitriou (1995) and the velocity dispersions from Walker et al. (2009a).
