Histogram showing the distribution of log₁₀ M_BH for sources presented in this work in red, Wójtowicz et al. (2023) in white, and early-type sources from van den Bosch (2016) in green in the top-right. Distribution of source distances (in Mpc), plotted on a logarithmic scale using the same color scheme in the top-left. The bottom-right and bottom-left histograms show the distributions of log₁₀ L_1.4 and L_1.4 GHz/L_Edd for sources from Wójtowicz et al. (2023) in white and this work in red, respectively.
