Radio luminosity L _R as a function of black hole mass M _BH. The filled circles represent the 3σ upper limit of L _R for each source, where the black hole masses are constrained via dynamical modelings. The dashed line represents the predicted L _R as a function of M _BH according to Strader et al. (2012). The dot–dashed line and the thick solid line correspond to our new results with δ = 0.1 and 0.001, respectively. The thin solid line and the dotted line represent L _R estimated by the relation instead of the fundamental plane relation with and without outflows, respectively.
