Global relations. The galaxy mass-to-light ratios, M/L_v (top panel) and the mode of their final metallicity distributions (bottom panel), versus their V-band luminosities L_V. Each circle stands for one of our 160 models, with c_⋆ and ϵ_SN restricted to the intervals 0.05−0.1 and 0.03−0.05, respectively. The central gas density and total mass range is 0.005−0.06   m_H/cm³ and 1−9 × 10⁸   M_⊙. Colors code the initial central gas density. The red large squares represent the Local Group classical dSphs, while the smallest red squares represent the ultra faint dwarfs. The dashed lines correspond to our best model fit. The green squares indicate the position of our selected generic models, from left to right, Carina, Sextans, Sculptor, and Fornax.
