Notes. 177 objects with λ estimates are divided into three subsets according to their value of λ. One source XID 5230 in the λH subset is excluded (see text). (1) Subset according to the classical Eddington ratio, λ. (2) λ range in logarithmic unit. (3) Number of sources. (4) Median black hole mass in logarithmic solar mass unit. (5) Median Eddington ratio λ in logarithmic unit. (6) Median redshift of the sources. (7) Median rest-frame 2–10 keV luminosity of the sources in logarithmic units of erg s-1. (8) Integrated rest-frame 2–10 keV flux of the stacked spectrum in units of 10-12 erg cm-2 s-1. (9) Arithmetic mean of the 2–10 keV flux per source in units of 10-13 erg cm-2 s-1. (10) Spectral slope of the stacked spectrum in the rest-frame 2–10 keV band. a: When absorption is included, a steeper value αE = 0.99 ± 0.19 is obtained with NH = (0.8 ± 0.64) × 1022 cm-2. (11) Comment on the Fe K feature.
