Notes. Tabulated parameters are the Einstein radius, θE, logarithmic slope of the mass profile, γ, the mass axis ratio, qm, the major axis position angle for mass, ϕm, the residual shear magnitude, γshear, the residual shear angle, ϕshear, the effective radius (i.e., half-light radius) of the light profile, Reff, the light axis ratio, qL, and the major axis position angle for light, ϕL. The angles ϕm, ϕshear, and ϕL are defined as north of east. The point estimates are obtained from the medians of the 1D marginalized posteriors, and the 1σ uncertainties are obtained from the 16th and 84th percentiles. The reported Reff for the lenses with a double Sérsic light profile was obtained by numerically solving for the half-light radius, and the effective qL for them was computed from the quadrupole moments of the double Sérsic profile. The statistical uncertainty levels are typical for lens models based on HST imaging (see, e.g., Tan et al. 2024). However, for Reff and γ we added 2% systematic uncertainty levels in quadrature following Shajib et al. (2019, 2021). The systems with missing γ measurements have them fixed at γ = 2 in their lens models.

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.
