The [O III] luminosity vs. velocity dispersion (left panel) and velocity shift (right panel). The Type 1 AGNs are plotted in red, while the Type 2 AGNs are in blue. The mean values in each L_{[O III]} bin are denoted by red (Type 1 AGNs), blue (Type 2 AGNs), and white (total sample) circles. The best-fit relation (left panel) for all objects (Type 1 and Type 2 AGNs), including the measurement error, is shown by the dashed line. In the right panel, the white circles are the mean V_{[O III]} at different L_{[O III]} bins for objects with V_{[O III]} measurement better than 1σ.
