Left panel: radio luminosity distribution of the FRIICAT (black, cyan for the HEGs) and FRICAT sources (red). The dotted vertical line indicates the transition power between FR I and FR II reported by Fanaroff & Riley (1974). Right panel: radio luminosity (NVSS) vs. host absolute magnitude, M_r, for FRIICAT and FRICAT (black and red, respectively; cyan for the HEG FR II). The dotted line shows the separation between FR I and FR II 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.
