Grid of lensing potential power spectra for the 15 possible auto- and cross-spectra of the five quadratic lensing estimators obtained from the SMICA foreground-cleaned maps. The measurements are arranged in order of their total S/N for a measurement of the lensing amplitude. The MV power spectrum estimate, which combines the individual cross-spectra and is the basis for our fiducial lensing likelihood, is plotted in the top-left panel.
