Radial profiles for Q_ϕ (red), StokesI (blue), and the degree of polarization Q_ϕ∕I (green) at a position angle of 200° for the ZIMPOL VBB observations (top) and for the IRDIS H-band observations (bottom). The intensity values on the vertical axis are in units of surface brightness relative to the total intensity of the system, i.e., [I_total∕arcsec²]. For the degree of polarization, only the values inside the cross-hatched boundaries with <0.5 error are shown in the plot to improve the visibility.
