Same as Fig. 2, but for the curved-ΛCDM cosmology, with fixed w = −1 and free Ω_m and Ω_k. Regions outside our priors on Ω_Λ (i.e. Ω_Λ < 0 or > 1) were not sampled and indicated in the panels. Although strong lensing only does not obtain stringent constraints on the curvature parameter, it is still complementary to other probes due to its perpendicular parameter degeneracies with respect to the CMB.
