Ratio of kinetic energy estimated from the velocity offsets and line widths, respectively, as a function of kinetic jet power. Filled dark blue and empty red circles show ratios derived with Eqs. (5) and (6) for 23 galaxies with extended emission-line regions in the present sample, respectively. We excluded RC 0311+0507 for which we only have [OII]λλ3727, 3729 with a composite line profile, unlike the other sources in our sample. Filled light blue dots and yellow open circles show the same estimates for nine galaxies with extended emission-line regions discussed in Collet et al. (2016), which have significantly lower radio power. The solid line shows the one-to-one relationship, dashed lines factors 4 above or below, which corresponds to twice the typcial uncertainty expected from inclination and resolution effects.
