continued. SL2S J09595+0218 (SA80) and SL2S J10021+0211 (SA83), left and right columns, respectively. First row: composite CFHTLS g, r, i color images (30″× 30″). Second row: identification of the arcs and their substructure in each lens (see Sect. 4.3). Third row: critical (red) and caustic lines (cyan) for the strong lensing models. The magenta circles show the measured positions of the image (input data for the model) and the green filled squares the model-predicted image positions. Fourth row: convergence maps. For a source located at the respective redshifts, z_s, given in Table 4. Dark gray lines shows κ = 1 for sources located in (z_phot − δz_phot, z_phot + δz_phot). Dotted blue lines and dashed blue lines depict the values for R_A, and θ_E,III, respectively.
