Bar fraction as a function of the AGN total disc accretion luminosity (L_disc) for X-ray (blue lines) and SED (orange circles) AGN. The f_bar is calculated for the S_bar and W_bar individually (left and middle panels, respectively), and for the total A_bar sample (right panel). The error bars are the same as in Fig. 13. Overlaid are the best-fit f_merg–L_disc relations from LM24 for the MIR (solid red line), X-ray (dotted-dashed blue line), and SED (dashed orange line) AGN, parametrised as described in Appendix C.
