Notes. Columns are as follows: (1): order number of the group. P denotes galaxies in poor groups. Main mark galaxies in the main body of the supercluster up to clustercentric distances 11.5 h−1 Mpc, and tail – galaxies with clustercentric distances larger than 11.5 h−1 Mpc; (2): ID of the group; (3–12): median values of galaxy parameters, and percentages of galaxies of high stellar mass, of old stellar populations according to the Dn(4000) index, red galaxies, passive galaxies, and galaxies with old stellar ages in a group. Values in parenthesis show (g − r)0 calculated including colours of possible group members missing because of fibre collisions. (13): magnitude gap between the two brightest galaxies in a group. For A2142 we give this for the BCG1 and BCG3 (Einasto et al. 2018).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
