Notes.

(a)

Taken from NASA/NED (The NASA/IPAC Extragalactic Database (NED) is funded by the National Aeronautics and Space Administration and operated by the California Institute of Technology),

(b)

in Mpc,

(c)

in units of 108 M,

(d)

in units of 1044 (erg/s),

(e)

in units of 10−3LEdd. DL, MBH, LBol, LXobs, Edd, and Γ are taken from K21b for Mrk 509, NGC 4151, and NGC 2617, while those for Mrk 142 are computed as explained in Sect. 6.6.
