Total luminosities (in the $V$ band) and half-light radii are from Wilkinson et~al. (\cite{Wilkinson06}), Wilkinson et~al. (\cite{Wilkinson04}), Koch et~al. (\cite{Koch07a}), Kleyna et~al. (\cite{Kleyna04}), Walker et~al. (\cite{Walker06}), Mateo (\cite{Mateo98}), Coleman et~al. (\cite{Coleman07}) and Irwin \& Hatzidimitriou (\cite{Irwin95}), for the galaxies in the table, in the order given, as summarised in Gilmore et~al. (\cite{Gilmore07}). Velocity dispersions are from adjusting a constant value to the data of Angus (\cite{Angus08}). $\langle \chi \rangle$ gives the average value of the parameter $\chi$ 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. (\cite{Hernandez00}), for Fornax from Coleman \& de~Jong (\cite{Coleman08}), for Draco from Aparicio et~al. (\cite{Aparicio01}), for Sextans from Lee et~al. (\cite{Lee03}), and for Sculptor from Babusiaux et~al. (\cite{Babusiaux05}).} \end{table}
