Notes. Column (1): absolute B-band magnitude at z = 0 used to select the sample with Eq. (6). Column (2): median luminosity of the sample in units of 
from AM14. Column (3): median number density of the sample. Column (4): observed cosmic variance. Column (5): galaxy bias measured from the cosmic variance. Column (6): galaxy bias measured from the two-point correlation function by AM14.
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.
