Fig. 6.

Top panel: radio luminosity obtained with the VLA at 15 GHz and the nuclear [OIII] emission line luminosity (Pearson correlation coefficient = 0.43, p-value = 2.6 × 10−6). Bottom panel: tighter correlation after including the mass of the black hole as the third parameter. This is the edge-on view of the optical fundamental plane obtained by using only the LLAGN sample (Pearson correlation coefficient = 0.74, p-value = 4.2 × 10−20). While the new detections reported in this paper are shown with filled circles, the old detections are depicted by open circles. Luminosities are given in erg s−1 while the masses are in units of solar mass.
