Simulated full-mission maps of HFI ADCNL at 143 GHz. Top row: full, unmitigated effect. Second row: residuals after fitting and correcting ADCNL using the linear gain model (first-order correction), as was done in PR3. Third row: residual after fitting for gain and distortion terms, as is done in NPIPE. The NPIPE transfer function (Sect. 4.3) applies to both the full and ADCNL-free simulations. Fourth and last row: half-ring, half-difference map from the same simulation to compare the magnitude of the effect to instrumental noise. All maps were smoothed with a 3° Gaussian beam. The residual power spectra are shown in Fig. F.2.
