Profile likelihoods (Δχ²) reconstructed for each ΛCDM cosmological parameter, from the CMB (blue) and CMB+BAO (red) data sets. Each point is the result of a 36-parameter minimization. We reject the points that are outliers of the expected distance to minimum (EDM, Sect. 2.2) distribution. Curves are fits to a third-order polynomial. 68% confidence intervals are obtained by thresholding these curves at unity, and their projections onto the parameter axis are shown.
