Notes. All velocity anisotropies are constant except Sculptor which is parametrised by 
. We found no significant decrease of χ2 for the other 4 dSphs by giving extra freedom to the velocity anisotropy. The values between parentheses in the M/L column are the M/Ls obtained from the widest and narrowest caustics.
