Planck 353 GHz angular power spectrum differences extrapolated to 150 GHz, computed from the following cross-spectra differences: DetSets minus Years (red squares); Years minus HalfRings (green stars); and HalfRings minus DetSets (blue circles). We also show the null test performed using the cross-DetSets spectra of the HalfRing half-differences (light grey triangle) and the cross-HalfRings of the DetSet half-differences (dark grey reversed triangle) at 353 GHz. As in Fig. 9, the blue boxes represent the statistical uncertainties from noise; these are centred on zero because we do not expect any signal for these null tests.
