Basic properties and resulting M/L ratios for the sample of dSph galaxies.

Galaxy				(M/L)A	(M/L)		Age of Youngest
							Component [Gyr]
Carina		0.290	4.3			7	3
Draco		0.230	2.6			4.1	10
LeoI		0.330	48.0			5.7	2
Sextans		0.630	5.0			13.4	(2-6)
Fornax		0.400	150.0			>3.4	(2-3)
Sculptor		0.160	22.0			>2.2	>5
LeoII		0.185	7.0			5.5	6.5
Ursa Minor		0.300	5.8			>5.3	12

Notes. (M/L)_A gives the values for the mass to light ratios calculated by Angus (2008), and M/L those in this study under the proposed model. Total luminosities (in the Vband) and half-light radii are from Wilkinson et al. (2006), Wilkinson et al. (2004), Koch et al. (2007a), Kleyna et al. (2004), Walker et al. (2006), Mateo (1998), Coleman et al. (2007) and Irwin & Hatzidimitriou (1995), for the galaxies in the table, in the order given, as summarised in Gilmore et al. (2007). Velocity dispersions are from adjusting a constant value to the data of Angus (2008). gives the average value of the parameter as defined in Sect. 2, which measures the relative relevance of the Newtonian and the low acceleration limit of the MOND formalism terms in Eq. (6). The final column gives an estimate of the age of the youngest stellar population present in each of the systems, for Carina, Ursa Minor, LeoI, and LeoII from Hernandez et al. (2000), for Fornax from Coleman & de Jong (2008), for Draco from Aparicio et al. (2001), for Sextans from Lee et al. (2003), and for Sculptor from Babusiaux et al. (2005).
