Distributions of galaxies and radio AGN in the ϵ-λ_Re plane. From left to right, the three panels show the distributions of galaxies in three M_⋆ bins: log(M_⋆/M_⊙) = 11.2 − 11.5, 11.5 − 1.8, and > 11.8. The total number of AGNs and galaxies within these M_⋆ ranges are 302 and 1329, respectively. The source number in each M_⋆ bin is listed in Table 1. The blue and red crosses mark the radio AGNs with log(L_150 MHz) = 21 − 24 and > 24, and the grey points denote the galaxies within the corresponding M_⋆ bin. The yellow lines denote the separation of SRs and FRs proposed by Cappellari (2016). The magenta line shows the estimated λ_Re of edge-on FR galaxies with maximum anisotropy δ = 0.7ϵ_intr described in Cappellari et al. (2007), where ϵ_intri denotes the intrinsic ellipticity. The grey dashed and dotted lines show the λ_Re for FRs with different inclinations and ϵ_intr, respectively.
