Notes. In parentheses, the number of objects used for the given average value is indicated.

^(a)

All objects in the sample have measured redshift and photon index (from a simple power law fit).

^(b)

Only objects having variability measured in both the 14–24 and the 35–100 keV bands have been considered here.
