Fig. 12.


Mass profile in terms of the critical surface mass density (κ computed at zs = 3) for the model that best reproduces the counter-images 4b and 7c (case 2b). The blue solid line is the mass density profile calculated with our method while the black dotted line is the dark matter mass density profile estimated after separating the stellar component of the BCG. The blue shaded region represents the 3σ uncertainty interval. The red dashed-dotted line is the best fit to a gNFW density profile achieved in this work while the green dashed line corresponds to a gNFW density profile considering the parameters attained in Caminha et al. (2017). The grey shaded area spreading from 7.8 kpc to 335.8 kpc (1.37″ to 59.1″) covers the region where all the multiple images considered in this work (and listed in Table B.1) are placed.
