Survey coverage (the colour scale represents integration time varying between 50 and 5000   s   deg^-2) for three individual detectors located near the edges (LFI-24 and LFI-25 at 44 GHz, top panels) and centre of the focal plane HFI 353-1 at 353 GHz, third panel). The maps are Mollweide projections of the whole sky in Galactic coordinates, pixelised according to the Healpix (Górski et al. 2005) scheme at N_side = 1024. The features due to “the day Planck stood still” and the Crab slow-down (Sect. 4.2) are pointed out as “S” and “C” respectively. The bottom panel is a zoom on the area around the North Ecliptic Pole, showing (in logarithmic scale) the distribution of high sensitivity observations integrated for all 100 GHz detectors.
