Notes. As a sanity check, SIS velocity dispersions are presented to compare with the measured velocity dispersions. The quasar redshifts and Einstein radii reported here have been used to calculate the SIS velocity dispersions. Note that, for B0445+123 and B0631+519, the source redshift is unknown. Thus a possible range of source redshift has been assumed to calculate the corresponding SIS velocity dispersion range.
Mean value of Einstein radius obtained by lens modeling in Schmidt et al. (2023) using HST images.
As detailed lens modeling for this system isn’t available, half of the quasar image separation measured from AO-based images was considered Einstein radius.
