... 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. ...

Prague, August 16, 2006 . Our trial revision of the GCVS data for several southern constellations show that type changes are not needed for most stars. ... We suggest to add one more symbol combining types, in the cases when two or more classification options remain for the same star, for example, EC|Ell, EC|RR (here EC means a contact eclipsing binary, this is one of our suggestions from next slides). ... Moreover, it will simplify moving stars from the suspected-variable catalogue to the GCVS. ...
