Notes. The number of galaxies with and without a measured velocity dispersion is given by and N^gal, respectively. For the latter, the number of galaxies, in BAYESLENS, that in principle are free to scatter around the best-fit σ-mag scaling relation is quoted in brackets. The systematic uncertainty assumed on galaxy positions is (Δx^gal)_sys. The quantity is the total number of observed multiple images, while (Δx^im)_st and (Δx^im)_sys are the statistical and systematic isotropic errors assumed on their positions. In the last two lines, the total chi-square and the rms displacement between the measured and model-predicted image positions are listed.
