Notes. For each selection method, in the upper row both Mvir and cvir were taken as free parameters, in the lower row the (Mvir, cvir, zcl) relation (Bullock et al. 2001) was used. The reduced χ2 was computed from the binned values displayed in Fig. 8. Also given are the values of M200: the larger uncertainties appear because they were derived from the fitted values (Mvir,cvir). The values of M2D before and after applying the factor 1.34 (Sect. 4.2) are displayed in the upper and lower rows, respectively.
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.
