Deflector redshift versus lens–lens angular separation for HSC J0233−0205 and a literature sample of close-pair lens systems from J. R. Lucey et al. (2018), Y. Shu et al. (2016), S. H. Suyu et al. (2010), S. Ertl et al. (2024), J. P. Willis et al. (2005), C. E. Rusu et al. (2014), and J. L. Tonry & C. S. Kochanek (1999). The yellow star marks the system presented in this work. The gray dashed curves indicate constant projected physical separations of 2, 4, 6, 8, and 10 kpc, from bottom to top. The red curve shows the angular separation corresponding to the projected deflector separation of HSC J0233−0205, 3.596 kpc, as a function of deflector redshift.
