Red-green-blue image of the central region of SDSS 2222, showing the multiply imaged sources that have been identified (see also Table 1). We overlay the best-fit critical curves at the quasar redshift (z = 2.801) from the models presented in this work. The solid and dashed lines display the critical curves for the associated models considering, respectively, the full and spectroscopic-only multiple image samples. The black cross indicates the reference position, corresponding to the luminosity centroid of the BCG (ID 2010), from which the cumulative projected total mass profiles are computed.
