For each frequency, EE power spectra are presented for the half-mission null-test difference maps, with and without noise. The plots show the data and five realizations of the ADCNL simulation: red with ADCNL and noise; orange with ADCNL without noise; green without ADCNL, but with noise; and purple without ADCNL, and without noise (residuals from other systematics). In the upper panels, no ADCNL correction has been carried out in the mapmaking, while in the lower panels, the time-varying gain correction has been applied. The simulations are also carried out without ADCNL.
