Notes. The upper and lower parts describe the lens and source catalogues, respectively. The a and s parameters enter the Lorentzian fitting function (see Eq. (10)) and capture the uncertainty on the redshift of our lens sample. The uncertainties on the mean redshift, Δ⟨z⟩, for the lenses are motivated by the uncertainty from the sources, although it is probably an upper limit of the error. We show the mean and uncertainty on the redshift bias for the source samples, taken from H21 and used in Asgari et al. (2021). The rightmost columns display the measured ellipticity dispersion per component, σϵ measured in Giblin et al. (2021), and the shear multiplicative m-bias correction updated in van den Busch et al. (2022).

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.

Initial download of the metrics may take a while.
