Notes. The radio-loudness parameter is from Bañados et al. (2021; and references therein), with the exception of POS352-15, where R2500 is from Rojas-Ruiz et al. (2021). Further references are: 1) Yi et al. (2014); 2) this work; 3) Bañados et al. (2015b); 4) Bañados et al. (2016); 5) Schneider et al. (2010); 6) Pâris et al. (2018); 7) Bañados et al. (2021); 8) Zeimann et al. (2011); 9) Roche et al. (2014); 10) Bañados et al. (2018b); 11) Jiang et al. (2009).
Classified as blazar (see Section 2 for details).
See Pâris et al. (2018) for a discussion on different redshift estimates.
We note J2053+0047 was reclassified as a RQ quasar with deeper radio VLA observations (see Section 2 for details).
Limit on radio-loudness parameter is obtained from Liu et al. (2021).
