Notes. Columns are (1) SARCS name; (2) spectroscopic redshift; (3) photometric redshift from Coupon et al. (2009); (4) average geometrical factor; (5) effective redshift derived from the average geometrical factor; (6) SIS velocity dispersion derived from the shear profile (quoted errors are the statistical uncertainties from the shear profile fitting); (7) arc radius (from More et al. 2012); (8) Einstein radius from σ_SIS and the source redshift in parenthesis (error bars account both for errors on σ_SIS and the PDF of z_s); (9–10) optical richness and luminosity derived from the bright red galaxies; (11–12) same as (9–10) but using an aperture of 1 Mpc.

^(*)

Groups that are closer to the edge of the field of view than the aperture in which richness and luminosity are estimated.

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.
