Cumulative distributions of the kinetic jet power for 431 low-excitation radio galaxies. The labels are the same as in Fig. 1. The kinetic jet power is derived from the NVSS 1.4 GHz kiloparsec-scale radio emissions. The average kinetic jet power for FR 0s is ⟨log L_0, kin⟩ = 42.93 ± 0.02 erg/s, while for FR Is, it is ⟨log L_I, kin⟩ = 43.86 ± 0.02 erg/s, and for FR IIs, it is ⟨log L_II, kin⟩ = 44.14 ± 0.03 erg/s.
