Notes. Information derived from the expert visual inspection of n = 30 000 randomly selected sources per magnitude bin. Uncertainties are given for a 68% confidence interval. Results are shown for both strong lensing in general, and for edge-on lenses only. If no candidates were found, the estimation corresponds to a prior-dominated upper bound. The names of the columns in parenthesis match the elements of Eq. (4).
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.
