14.4 Comparison with external catalogues

14.4.8 QSOs and galaxies

Galaxy profiles are compared with the GAMA (Kelvin et al. 2012) Sérsic profiles and with the SDSS DR16 (Ahumada et al. 2020) de Vaucouleurs profiles. Galaxy redshifts are compared with SDSS DR16 (Ahumada et al. 2020), 2MASS MRS (Huchra et al. 2012), GAMA (Liske et al. 2015) and 6df (Jones et al. 2009) catalogues. QSO redshifts are compared with the LQAC5 (Souchay et al. 2019), SDSS DR14 (Pâris et al. 2014), 2df (Croom et al. 2004), GaiaunWISE (Shu et al. 2019), GIQC (Andrei et al. 2014), milliquas (Flesch 2021) and Taris et al. (2013). DSC classifications probabilities and variability scores are also compared with those catalogues.
