Mass maps inferred from the cored (yellow), the non-cored (green) and the NFW (magenta) models. Contours show where the surface mass density equals 4, 7 × 10¹⁰ M_⊙ arcsec^-2. Red diamonds correspond to the light peaks associated with each mass component. The white cross shows the barycentre of the Einstein ring as estimated by Meneghetti et al. (2011) at α = 109.38002,δ = 37.752214. The underlying image covers an area of 236′′× 166′′.
