Power spectra of the 100-GHz half-mission null-test maps shown in Fig. B.14, which are dominated by ADC non-linearity effects. We compare six simulations at 100 GHz drawn from the Sroll uncertainties (red lines), and the average for the full frequency 100-GHz data (blue line). In the top panel only the TOI non-linearity correction is applied. In the bottom panel, both the TOI correction and the time-varying gain correction are applied. This leaves only the dipole distortion. For both panels the green lines are for simulations without the ADC non-linearity effect (only noise and other systematic residuals).
