Comparison of the tSZ angular power spectrum estimated from the cross-power-spectrum of the NILC (left) and MILCA (right) F/L maps (black), with the expected angular power spectrum of the confirmed clusters in the Planck Cluster Sample (green solid line). The angular cross-power spectrum between the NILCA and MILCA Compton parameter maps and the simulated detected cluster map is shown in red. The correlation between the reconstructed y-map and the simulated detected cluster map, to which an arbitrary rotation has been applied, is plotted in grey (negative values dashed–lines for the error bars).
