Notes. Columns are the baryonic mass, the luminous effective radius, the core radius r0 and the asymptotic velocity v0 of the log-halo, its surface density, central density and phase space density, the latter as defined by G01. The parameters have been obtained from fits out to two effective radii. The last column gives the acceleration in units of a0 at a radius of 2 Reff for each Hernquist model. The predictions for MONDian halos in the previous columns are only valid for galaxies embedded in an external field weaker than this value.
