 | \Planck\ 2015 temperature power spectrum. At multipoles $\ell\ge30$ we show the maximum likelihood frequency-averaged temperature spectrum computed from the \plik\ cross-half-mission likelihood, with foreground and other nuisance parameters determined from the MCMC analysis of the base \LCDM\ cosmology. In the multipole range $2 \le \ell \le 29$, we plot the power spectrum estimates from the {\tt Commander} component-separation algorithm, computed over 94\,\% of the sky. The best-fit base \LCDM\ theoretical spectrum fitted to the \planckTT\ likelihood is plotted in the upper panel. Residuals with respect to this model are shown in the lower panel. The error bars show $\pm 1\,\sigma$ uncertainties. |
