Notes. The subscripts ‘SCl’ and ‘GRG’ indicate host supercluster and GRG properties, respectively. Column 1 (SCl) is the supercluster identification number from SSC23. The other columns include RA, Dec (right ascension and declination), z (redshift), CoSize (comoving size), Size (projected physical size), Mass (supercluster mass), NMem (number of member clusters), and δ (density contrast of the supercluster). The coordinates of GRGs (3 in each) located in SCl 2 (see Fig. 1) and SCl 73 are highlighted in bold. The last column, EnvGRG, categorises the environment of the GRG: BCG indicates the GRG is central within a BCG-hosted galaxy cluster (47 sources), No-Cl denotes GRGs outside any galaxy cluster (23 sources), and Mem-Cl signifies GRGs residing within a galaxy cluster (7 sources) that are not BCGs. zGRG with † indicates photometric redshift. Redshift information for GRGs has been sourced from their respective reporting catalogues, which are primarily derived from the SDSS (York et al. 2000).

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.
