Notes. The total masses for WBL154 and A3390 (marked with a star) which show a double peak have been calculated by summing up the total mass of each of their two components. The R500 and R2500 have been then estimated from their total M500 and M2500, respectively. Rspec is the radius within which the global temperature of the object has been determined. LX,xmm is the luminosity in the 0.1–2.4 keV band.
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.
