Notes. Column 1: source name (J2000, * indicates unknown redshift) and component (U ≡ no clearly resolved second component). 2: Proposed morphological classification. 3: Integrated flux density at 1.55 GHz. 4: Integrated flux density at 4.96 GHz. 5: Optically thin spectral index, measured between 1.55 and 4.96 GHz for resolved components. 6: Effective deconvolved major axis of the component, with error approximated as the same relative error from Sect. 3. 7: Effective deconvolved minor axis. 8: Magnetic field assuming SSA calculated from Eq. (3) (an overestimate for unresolved components). 9: Magnetic field assuming equipartition conditions calculated from Eq. (4) (an underestimate for unresolved components). For components of resolved sources BSSA has been calculated assuming Speak is approximately the total flux density at νpeak. If we instead assume the power-law derived from 1.55 and 4.96 GHz VLBA flux densities holds at νpeak, BSSA for the Western and Eastern components of J0231−0433, J0235−0100, and J1509+1406 would be 0.04, 7, 4, 6, 0.9, and 0.2 mG, respectively, which still underestimate BEqui.
