Comparison of the best-fit correlation coefficients, ξ_X and ξ_M, of the fundamental plane for Eddington ratio subsamples (A), redshift subsamples (B), and galaxy star formation property subsamples (C). The theoretically predicted correlation coefficients for ADAF, the synchrotron jet model, and the disc model are the same as in Fig. 4, and are shown here as circles, triangles, and squares, respectively. In each panel, filled symbols represent radio-quiet (RQ) AGNs and empty symbols represent radio-loud (RL) AGNs. In panel A, “TW”, “B22”, “D14”, “W06”, and “L08” mean results from this work, Bariuan et al. (2022), Dong et al. (2014), Wang et al. (2006), and Li et al. (2008), respectively. Different colors represent different Eddington ratios: red for ${\overline{\lambda }}_{\mathrm{Edd}}<0.01$, yellow for $0.01<{\overline{\lambda }}_{\mathrm{Edd}}<0.05$, green for $0.05<{\overline{\lambda }}_{\mathrm{Edd}}<0.1$, blue for $0.1<{\overline{\lambda }}_{\mathrm{Edd}}<0.5$, and violet for ${\overline{\lambda }}_{\mathrm{Edd}}>0.5$. In addition, our results (TW) are labeled by big gray circles.
