Notes. We distinguish between lens candidates classified as clusters during visual inspection (see Sect. 4.2) and based on galaxy catalogs (Oguri 2014; Oguri et al. 2018; Wen & Han 2018, 2021). Without photo-z selection (see No. 0), we visually identified 84 lens candidates to be in an overdense environment, while 174 lens candidates are located closer than 100″ from a known galaxy cluster. We highlight No. 46 in bold, which has the selection criteria cuts that are the best according to the F1tot statistic.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
