Notes. (1) Method used to model the system, (2) Einstein radius in arc second, (3) average magnification of the source, (4) redshift of the source and its uncertainty used to estimate Mtot(θEin), and (5) total mass of the lens within the Einstein radius. The mass is always estimated using zlens = 2.00 ± 0.02. Uncertainties on the mass are evaluated by averaging 1000 Monte-Carlo realizations using the uncertainties on the Einstein radius, source redshift, and lens redshift. For PYAUTOLENS, we give the two different magnifications found in the F444W and F115W bands, respectively. Text in boldface represents values used as reference in the analysis.
