For each of the four frequencies, we show eight Q maps. The first row contains data (left column) and one realization of simulation of the ADCNL with noise (centre column) and without noise included (right column). The second row contains the same after correction for the ADCNL linear gain variation. The third row for each frequency contains simulations carried out without including the ADCNL. With the strong ADCNL signal (especially the dipole part) absent, these show the noise plus other systematics (centre) and just the systematics (right).
