Comparison of the stellar properties of the six Local Group dwarf galaxies: NGC 6822, Andromeda II, Sculptor, Sextans, Ursa Minor and Draco. The model id, the model galaxy total mass (M200), total luminosity (LV), and total stellar mass (M), which are calculated inside the virial radius R200 are indicated on the upper left-hand side of each series of four panels. For each galaxy, the upper left panel displays the model star formation history. The lower left panel shows the line of sight velocity dispersion of the model galaxy in blue, as compared to the observations (red shaded area). The black line corresponds to the total circular velocity. The upper right panel displays the model galaxy stellar metallicity distribution. The lower right panel gives the galaxy [Mg/Fe] vs [Fe/H] distribution. In both quadrants, the model is seen in blue and the observations in red.
