Notes. Columns: NG: number of galaxies in the group; z: redshift (spectroscopic); D: approximate distance to the system, calculated from redshift, assuming H0 = 73 km s−1 Mpc−1; σV: velocity dispersion; Φ: physical diameter of the system (from optical data). The last four columns contain the flux densities from the respective survey data.
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.
Initial download of the metrics may take a while.
