Notes. Right ascension and declination are from the Gaia DR2 catalogue. Optical magnitudes are in the AB system and are from the SDSS photometric data. The MIR W1−W2 colours are from the AllWISE catalogue and are in the Vega system. Spectroscopic redshifts are based on the already identified quasars in the SDSS-DR14 quasar survey (Pâris et al. 2018) or the NED database (specifically from Crampton et al. 1987). Photometric redshifts (marked by a “P”) are from Richards et al. (2009). The full table is available in Appendix A.
