Sample selection of the SLACS lenses being added to the analysis and comparison with the TDCOSMO data set. The comparisons are in lens redshift, z_lens, source redshift, z_source, measured velocity dispersion, σ^P, half light radius of the deflector, r_eff, Einstein radius of the deflector, θ_E, the ratio of half light radius to Einstein radius, r_eff/θ_E, and the SIS equivalent velocity dispersion estimated from the Einstein radius and a fiducial cosmology, σ_SIS. Open dots correspond to lenses included in our selection without quality lens models. Red points correspond to SLACS lenses which have VIMOS IFU data (https://github.com/TDCOSMO/hierarchy_analysis_2020_public/blob/6c293af582c398a5c9de60a51cb0c44432a3c598/JointAnalysis/sample_selection.ipynb).
