Notes. The columns give the sample name, the survey area covered, the number of galaxies Ngal used to compute both the galaxy number densities and the shapes, the mean redshift ⟨z⟩, and the mean luminosity ⟨L⟩/L0 in terms of a fiducial luminosity L0 that corresponds to a k + e-corrected (to z = 0) absolute r band magnitude M0 = − 22.
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.
