Planck+WP+highL data combination (samples; colour-coded by the value of H₀) partially breaks the geometric degeneracy between Ω_m and Ω_Λ due to the effect of lensing in the temperature power spectrum. These limits are significantly improved by the inclusion of the Planck lensing reconstruction (black contours). Combining also with BAO (right; solid blue contours) tightly constrains the geometry to be nearly flat.
