Notes. The last column represents the name of the survey or the instrument used to improve the catalogue of spectroscopic systems. Some studies use the same data but differ in the number of systems and images, either due to different quality assessments or due to the inclusion of multiply imaged clumps within a single background galaxy. The number does not include systems without spectroscopic redshifts, which were also used to constrain the lens model in some works (e.g. Di24). Note that the last line (this work – all) also includes images from the quartz catalogue with MUSE redshift, which are not used for lens modelling.
