Impact of the angular diameter distance to last scattering, D _A , and the lensing information on the curvature constraint from the CMB. The contours show the 68% and 95% C.L. contours when lensing information is included. The colored points are samples from the posterior distribution after marginalizing over A _L , which effectively removes all lensing information. The allowed range of values remains finite in the absence of lensing information, because the CMB still places (weaker) constraints on the ΛCDM+Ω _k model parameters. The color reflects the curvature value as indicated by the color bar on the right side of the plot. The lensing sensitivity of the data is clearly crucial to the curvature constraint from the CMB data.
