Fig. 1
0.1−2.4 keV X-ray vs. 20 cm FIRST peak luminosity. Symbols of our sources are indicated in the legend and correspond to spectroscopic types. Colors are coded according to the black-hole mass. Open symbols are for objects without available black-hole mass. For comparison, we present SDSS/FIRST/ROSAT-based broad-line AGN (BLAGN) from Li et al. (2008, × correspond to RQ and +. The dashed line is the linear correlation for RQ QSO of Brinkmann et al. (2000).
