Notes. Columns: (1) (Sub)sample; (2) number of sources; (3) number of net counts in 2 − 12 keV rest-frame; (4) number of net counts in 5 − 8 keV rest frame; (5) average redshift; (6) average rest-frame 2 − 10 keV luminosity in units of 1043 erg s-1, corrected for Galactic and intrinsic absorption∗; (7) average intrinsic column density in 1022 cm-2∗; (8) gamma from the fit of the average observed spectrum with a powerlaw between 2 and 5 keV (rest-frame); (9) χ2/d.o.f. of the fit of the average observed spectrum with a powerlaw between 2 and 5 keV (rest-frame); (10) slope of the powerlaw ∗∗ of the average spectrum obtained with the simulations of the Fe line (see text); (11) width obtained in those simulations; (12) EW of the line obtained from those simulations.
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.
