. Comment on J1720-0058 . Resolved: this FR-II radio galaxy is not detected at 2.3 GHz by Preston et al. (1985). A VLA map at 8.4 GHz is published by Swain, Bridle & Baum (1998). However, there is correlated signal at the shortest baselines from which a position has been derived and is listed in the table. Our best guess is that the residual core has a flux density of 0.15 Jy and a size of ~15 mas. See Figure 3. VLBApls home page . Last modified: 16 Oct 2000

... All the galaxies are divided into 4 groups depending on the environment type; every subsample contains more than 10 galaxies. ... An effect of environments is seen both for the nuclei and for the bulges: if we consider the clusters (Virgo and Ursa Ma jor) and group centers as dense environments and the field and group periphery as sparse environments, then in the dense environments the stellar populations of S0s are in average older by 4­5 Gyr than in the sparse ones. ...
