The radio core luminosity (L_{Radio, core}) against (a) the size of the bulge as measured by its effective (half-light) radius R_e, (b) the bulge-to-total light ratio (B/T) and (c) the average ellipticity within R_e calculated excluding the most-PSF affected data points inside . The dotted curves trace the mean trend. Apparent is the tendency for galaxies with brighter radio core luminosities to be bulge prominent, round, and with large bulge sizes. A representative error bar is shown at the bottom of each panel.
