Notes. Column description: 1) name; 2) alternative name; 3) spectroscopic redshift from the NED database; 4) distance in Mpc ( ± 0.5 Mpc) from Mei et al. (2007); 5) sub-cluster to which each galaxy belongs, with the dominant galaxies marked; 6) and 7) three dimensional distance (Mpc) and velocity (km s-1) along the line of sight with respect to the dominant components of the sub-clusters Virgo A or B; 8) radio core luminosity (ergs-1Hz-1) from Capetti et al. (2009); for NGC 4636 we adopted the value of BBC08, adjusted at the distance assumed in this paper; 9) mass of the central SMBH in units of M⊙ derived from the stellar velocity dispersion reported in the HyperLeda database or from direct measurements as listed by Marconi & Hunt (2003) (when not reported, we adopt an intrinsic error of ± 0.23 dex, related to the dispersion of the MBH − σ∗ relation). (a) For this object there is no distance measurement thus we adopted the average Virgo distance to estimate luminosities; accordingly its three dimensional distance d from the cluster is a lower limit, equal to the offset from M 49 in the plane of the sky. (b) The distance of NGC 4636, with an associated error of ± 0.9 Mpc, is from Tonry et al. (2001), scaled by a factor 1.06, the average ratio between the distances of Tonry et al. (2001) and Mei et al. (2007) for our sample.
