Notes. Column description: (1) parameter; (2–3) average value for the FR 0s, the FR Is (split into (4 and 5) FRICAT and sFRICAT sources); (6 and 7) median value for the FR 0s, the FR Is (split into (8 and 9) FRICAT and sFRICAT sources) (10) outcome of the Kolmogoroff-Smirnov test (and corresponding probability) T= the FR 0 and FR I populations differ significantly. The parameters considered are the redshift (z), the absolute magnitude of the source (Mr), the number of cosmological neighbors within 2 Mpc () and 1 Mpc (), the number of galaxies (Ngal) associated with the groups and clusters hosting the radio sources according to T12, the fifth nearest neighbor density (Σ5), the number of cosmological neighbors within 2 Mpc () when all sources are moved to a common redshift of 0.05, the projected distance in kiloparsec (), and the absolute value of the speed of light times the redshift difference in km s−1 (|cΔz|) from the average of the cosmological neighbors.

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.
