Fits to the joint likelihoods for Planck and SPT S12 spectra. a) Fits using only the 143 × 143 GHz spectrum in the Planck likelihood. The blue points show the SPT data after recalibration and foreground subtraction, using the best-fit solution from the joint likelihood analysis. The magenta points show the foreground-subtracted Planck143 × 143 GHz spectrum. The lower panel shows the residuals with respect to the best-fit ΛCDM model to the Planck+SPT combined likelihoods (shown by the red line in the top panel). b) Foreground-subtracted and recalibrated SPT spectra using the best-fit parameters from the likelihood analysis of the full Planck likelihood combined with the SPT S12 likelihood. The magenta points show the best-fit PlanckΛCDM spectrum from Fig. 10 and the red line shows the best-fit Planck+WP+highL base ΛCDM model from the full Planck likelihood. The residuals with respect to this model are plotted in the lower panel.
