Notes. Median properties, with the 16th and 84th percentiles, of the FR and COM AGN at 3 GHz VLA-COSMOS. We note that λrk values are consistent with face-on radio jets (low inclination with respect to the observer’s line of sight), while the kinetic component could drop by > 100 times at higher inclinations, converging to the λr values. We have also calculated the median D using the LAS from the semi-automatic ML method (for the secure measurements) presented in Appendix C, in combination with the by-hand measurements for non-secure measurements. The results are similar to the median D derived with the by-hand only measured LAS: DFRII = 105.6
kpc; DFRI/FRII = 37.5
kpc; DFRI = 29.0
kpc. The median D values derived by using the combination of the ML and by-hand methods are up to ∼1 kpc smaller than the values calculated with the by-hand LAS measurements alone. This is related to the semi-automatic method underestimating the sizes in cases of diffuse radio emission.
