[O III] line width described by W₈₀ against AGN bolometric [O III] luminosity (left panel) and BLR Hβ luminosity (right panel). The yellow circles denote the type 2 AGN sample from Liu et al. (2013a), the blue diamonds denote the type 2 AGN sample by Harrison et al. (2014), the lime triangles denote the type 2 AGN sample by Sun et al. (2017) and the red stars denote our CARS sample of type 1 AGN. The dense scatter plot corresponds to the overall SDSS sample of both type 1 and type 2 (left panel) and type 1 AGN (right panel) from the ALPAKA library published by Mullaney et al. (2013).
