Notes. z_s and z_l are the redshifts of the double quasar (images A and B) and the main lensing galaxy G, respectively. Additionally, regarding the two astro-photometric solutions APS 1 and APS 2, the brightest image A is located at the origin of coordinates, and the positive direction of x is defined by west, while the positive direction of y is defined by north. Some astrometric errors were also made symmetric (σ_x = σ_y). The morphology of G (De Vaucouleurs brightness profile) is given by three parameters: the ellipticity (e_G), the position angle of the major axis (θ_eG; it is measured east of north), and the effective radius (R_G). We also include the macro-magnification ratio M and time delay Δt with respect to the image A. All astro-photometric, magnification, and delay constraints are 1σ confidence intervals. The last three rows correspond to the external convergence, the external shear strength, and the position angle of the external shear. We also assumed a flat ΛCDM cosmology (see main text).
