Confidence levels (black lines) for the cosmological parameters of models W1 and W2 (Ω_m + Ω_Λ = 1, top panels) and L1 and L2 (w = −1, bottom panels). Left panels refer to strong lensing models using only spectroscopic families (L1, W1); models in the right panels include all families (L2, W2). Red lines: contours from Planck Data Release 2 data. Blue regions: combined constraints. The yellow circles indicate the maximum likelihood peak in this projection.
