Distributions of the lensing properties of the strongly lensed L₂ systems from detections in each of the u, g, r and i bands after applying image separation cuts and LSST1 magnitude cuts. Top panels from left to right: lens galaxy redshift z_l, TDE redshift z_s, and image separation θ_sep. Bottom panels from left to right: lensed magnitude (magnitude of the fainter image in a double system or the third brightest image in a quadruple system), stellar velocity dispersion σ of the lens galaxy, and time delays t_delay of all images in the lensed systems.
