Non-oriented stacks of intensity T (left), reconstructed E-mode (centre) and B-mode (right) polarization stacked on intensity maxima for the CMB (top row, SMICA map at N_side = 1024 and 10′ FWHM beam), low-frequency foregrounds (middle row, LFI 30-GHz map smoothed using a 10′ FWHM beam, with subtraction of the SMICA CMB map at 10′ FWHM resolution smoothed by the 30-GHz LFI beam), and high-frequency foregrounds (bottom row, 353-GHz HFI polarization-sensitive bolometer map smoothed using a 10′ FWHM beam, with subtraction of the SMICA CMB map at 10′ FWHM resolution smoothed by the 353-GHz HFI beam). The common temperature mask was used for temperature peak selection, and the polarization confidence mask of Appendix A was used for E- and B-mode stacks.
