Notes. The levels reported in this table correspond to the amplitude of the contamination, , at ℓ = 200 in μ. They are obtained at each frequency by fitting the 545 GHz cross half-mission spectra against the CMB-corrected 545 × 100, 545 × 143 and 545 × 217 spectra over a range of multipoles. The CMB correction is obtained using the 100 GHz cross half-mission spectra. This contamination is dominated by dust, with a small CIB contribution. The columns labelled with a Galactic mask name (G41, G50, G60, and G70) correspond to the results when combining those masks with the same CO, extended object, and frequency-combined point-source masks. The CIB contribution is shown in the last column. The errors quoted here include the variation when changing the range of multipoles used from 30 ≤ ℓ ≤ 1000 to 30 ≤ ℓ ≤ 500.
