The [O III] velocity dispersion (top), dispersion ratio (middle), and velocity shift (bottom) as a function of luminosity at 1.4 GHz (left panels) and the luminosity ratio of 1.4 GHz to [O III] (right panels) for Type 1 AGNs. The mean values at each bin along the x-axis are shown along with the 1σ dispersion. In the plot, σ_gr = σ_{[O III],narrow} is considered.
