Fig. 10.

Left panel: host absolute magnitude (Mr) vs. radio luminosity (NVSS) at 1.4 GHz, for WATCAT, FRICAT, and FRIICAT sources (green diamonds, black dots, and red squares, respectively). The dashed blue line shows the separation between FR I and FR II, as reported by Ledlow & Owen (1996), to which we applied a correction of 0.34 mag to account for the different magnitude definition and the color transformation between the SDSS and Cousin systems. The bulk of the WATCAT sources lies below the boundary between FR I and FR II radio galaxies. Right panel: radio luminosity (NVSS) at 1.4 GHz vs. black hole mass for WATCAT, FRICAT, and FRIICAT (green diamonds, black dots, and red squares, respectively). WATs and FR Is show similar black holes masses, but WATs are more radio luminous.
