Distributions of photometric redshift and i–band magnitude of the lens galaxies in galaxy-scale strong-lens candidates from the SuG-OHI project (yellow), C21 (blue), and this work (red). The contours correspond to 10th, 30th, 50th, 70th, and 90th percentiles of the individual samples. To make a fair comparison, we use photoz_best from the pdr2_wide.photoz_mizuki table for SuGOHI lens galaxies instead of the photometric redshifts provided by the SuGOHI project website².
