Kinetic jet power versus black holes. (1) Upper panel: 431 low-excitation radio galaxies. The black triangle is for FR 0s, the red circle is for FR Is, and the blue diamond is for FR IIs. (2) Lower panel: 75 Fermi BL Lacertae objects. The yellow triangle is for LBLs, the purple square is for IBLs, and the green pentagon is for HBLs. Their intrinsic kinetic jet power is obtained assuming a Doppler factor of δ ∼ 10 within the continuous jet model (p = 2 + α) and the flat spectral index (α = 0). The solid black line is for the maximum jet power in the Blandford-Znajek (BZ) jet model; the dashed red line is the mixture (hybrid) of the BZ and Blandford-Payne jet models; the average uncertainty for BH mass is 0.25 dex, and the average jet power uncertainty is 0.7 dex.
