0.1–2.4 keV X-ray luminosity vs. redshift for the broad emission line AGN sample in SDSS DR5 determined by Anderson et al. (2007). Black symbols show objects in the redshift range 0.16 < z < 0.36, which define the AGN sample used here. The dashed line corresponds to the common dividing line between low luminous AGNs and high luminous QSOs ( L ^{0.5–10 keV} _X = 10 ⁴⁴ erg s ⁻¹) defining the low and high luminosity RASS-AGN samples used here.
