Notes. L43: luminosity in units of 1043 erg s-1. Columns: (1) (Sub)sample; (2) number of sources; (3) number of counts in 2 − 12 keV; (4) number of counts in 5 − 8 keV; (5) average redshift; (6) average luminosity in 1043 erg s-1; (7) average column density of the local absorber in 1022 cm-2; (8) significance of the Fe line calculated as the number of average simulated spectra with a lower flux than the flux of the average observed spectrum (calculation made between between 6.2 and 6.6 keV).

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.
