Table 2: Mass estimates for the Carina, Sculptor and Fornax dSphs. The quantities labelled with $^{\rm min}$ are lower limits for the mass and M/L obtained by assuming a circular orbit. The quantities labelled $^{\rm best}$ give a "best guess'' based on almost random, but conservative assumptions for the orbits. Also given are the heliocentric distance, the kinematic M/L and the heliocentric velocity.
