Polarized intensity images Qφ(x,y) and Uφ(x,y) for V, I′, J, and Ks band. All images are normalized to the integrated stellar intensity I★ and their pixel scale (3.6 × 3.6 mas2 for ZIMPOL and 12.25 × 12.25 mas2 for IRDIS). The shared color bar is indicated on the right. All the images are cut to 1.0 × 1.0″ and the black bar in Qφ(V) indicates 0.2″. The dashed lines in Uφ(V) enclose the integration region for the cavity, the rim, and the spiral respectively. The semitransparent circle in K-hop represents the inner working angle (IWA) = 0.125″ limited by the coronagraph. North is up and east to the left.
