Mueller matrix model-corrected IRDIS-DPI Q_φ (left), U_φ (middle) and polarized intensity (right) images. North is up, east is left. Note that the Q_φ and U_φ images are not normalized/saturated here on purpose to emphasize their partially negative signal. The inner 0.̋18 are masked, represented by the black circular area. The orange stripes in the right image represent the angle of linear polarization (fixed length, not scaled with the degree of polarization).
