Left: zone masks constructed from the filament masks and the Galactic masks. The area covered by the PCCS2 is given by the zero (blue) values in the mask, and that covered by the PCCS2E is given by the non-zero values. The Galactic region is traced in red, and the filament mask is yellow outside the Galactic region and green inside it. Centre: rms noise level as determined by the HFI MHW2 code. Right: S/N thresholds applied to the raw catalogue; a flat S/N cut is applied in the region of the PCCS2E and for the PCCS2 at 545 and 857 GHz.
