Notes.Columns are (1) name of the stack; (2) selection criterion; (3) number of lenses in the stack; (4) average redshift; (5)−(6) average richness and optical luminosity within 1 Mpc (red sequence galaxies, Mi′< −21); (7) average weak-lensing SIS velocity dispersion; (8) average arc radius. Means were derived using the groups’ individual properties given in Paper I. Note: 2 objects with no estimate of RA were not included in the R-stacks.
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.
