Noise spectra computed from difference maps for a selection of detector sets: 100GHz (top), 143GHz (middle), and 217GHz(bottom). Green lines show the spectra for T, purple for Q and magenta points for U. The solid black lines show the modeled fits to the spectra (Eq. (A.46)), and the coloured horizonal lines show the white-noise levels of Eq. (A.44). These are computed using the same masks as used in Table A.1.
