Comparison of the stellar velocity dispersions measurement used in this paper and those in TDCOSMO-4 and Wong et al. (2024, for WGD 2038−4008). Note that the measurement apertures and PSF resolutions differ between those presented in this paper and those in previous ones. Thus, the measurements are not expected to match exactly. For RX J1131−1231, we illustrate here the value reported in Table A.1 that corresponds to the stellar velocity dispersion measured within half the effective radius.
