We compiled a sample of 24 flat-spectrum radio quasars (FSRQs), 21 BL Lacs, 13 FRI and 12 FRII radio galaxies to study the jet power and broad-line luminosity relation, and the jet power and black hole mass relation. Furthermore, we obtain the histograms of key parameters. Our main results are as follows: (i) We found that the FSRQs are roughly separated from BL Lacs by the Ledlow–Owen FRI/FRII dividing...
