Consistency check at the power spectrum level between half-ring difference maps (red), white-noise covariance matrices (black dash-dotted lines), and 100 full-noise MC simulations (grey band showing range for 16% and 84% quantiles of noise simulations, and the black solid lines giving the median, i.e., 50% quantile, of the distributions). From top to bottom we show TT, EE, and BB power spectra for 30 GHz (left), 44 GHz (centre), and 70 GHz (right). Half-ring spectra are binned with Δ = 25 for  ≥ 75.
