The catalog includes sources with redshift ≤0.15, an edge-brightened radio morphology, and those with at least one of the emission peaks located at radius r larger than 30 kpc from the center of the host. The radio luminosity at 1.4GHz of the FRIICAT sources covers the range L1.4∼1039.5-1042.5erg/s. The FRIICAT catalog has 90% of low and 10% of high excitation galaxies (LEGs and HEGs), respectively. The properties of these two classes are significantly different. The FRIICAT LEGs are mostly luminous (-20≳Mr≳-24), red early-type galaxies with black hole masses in the range 108≲MBH≲109M; they are essentially indistinguishable from the FR Is belonging to the FRICAT. The HEG FR IIs are associated with optically bluer and mid-IR redder hosts than the LEG FR IIs and to galaxies and black holes that are smaller, on average, by a factor ∼2. FR IIs have a factor ∼3higher average radio luminosity than FR Is. Nonetheless, most (∼90%) of the selected FR IIs have a radio power that is lower, by as much as a factor of ∼100, than the transition value between FR Is and FR IIs found in the 3C sample. The correspondence between the morphological classification of FR I and FR II and the separation in radio power disappears when including sources selected at low radio flux thresholds, which is in line with previous results. In conclusion, a radio source produced by a low power jet can be edge brightened or edge darkened, and the outcome is not related to differences in the optical properties of the host galaxy. Description: We searched for FR II radio galaxies in the sample of 18,286 radio sources built by Best & Heckman (2012, Cat. J/MNRAS/421/1569; hereafter the BH12 sample) by limiting our search to the subsample of objects in which, according to these authors, the radio emission is produced by an active nucleus. They cross-matched the optical spectroscopic catalogs produced by the group from the Max Planck Institute for Astrophysics and Johns Hopkins University (Brinchmann et al. 2004MNRAS.351.1151B; Tremonti et al. 2004ApJ...613..898T) based on data from the data release 7 of the Sloan Digital Sky Survey (DR7/SDSS; Abazajian et al. 2009ApJS..182..543A),1 with the National Radio Astronomy Observatory Very Large Array Sky Survey (NVSS; Condon et al. 1998AJ....115.1693C, Cat. VIII/65) and the Faint Images of the Radio Sky at Twenty centimeters survey (FIRST; Becker et al. 1995ApJ...450..559B; Helfand et al. 2015ApJ...801...26H, Cat. VIII/92) adopting a radio flux density limit of 5 mJy in the NVSS. We focused on the sources with redshift z<0.15. The majority (107) of the selected FR IIs are classified as LEG, but there are also 14 HEG and just one source that cannot be classified spectroscopically because of the lack of emission lines, namely J1446+2142.
