Consistency between data and simulations as quantified in terms of pixel-space variance for both temperature (left panel) and polarization (right panel), and for both full mission maps (top row), half difference maps (middle two rows), and for half-mission and odd-even cross variances (bottom two rows). Coloured lines show results for the four different component-separation pipelines, Commander (red), SMICA (cyan), SEVEM (green), and NILC (orange), as a function of pixel resolution, N_side.
