Maps corresponding to the modified Stokes I, q, and u from left to right. Top: data from the S2 simulation downgraded to N_side = 64; second row: best-fit maps obtained while assuming the dust distribution follows an ED model (case B); third row: best-fit maps obtained while assuming the dust distribution follows an ARM4 model (case C). The two last rows show the significance of the residuals for the case B (4th row) and the case C (5th row). For the case B, the color scales range from −500 and 500 and from −15 to 15 for the intensity and the polarization, respectively. For the case C, color scales range from −5 to 5, as in Fig. 4.
