Synthetic observations of our PDS 453 model with a single zone, with similar scales and stretches as in Fig. 1 and Fig. 4. All images have been convolved by the appropriate PSF after subtracting the central point source to mimic the effect of the coronagraph. Left panel: Scattered-light 1.6 µm polarized intensity image shown a the SPHERE resolution. Middle panel: Scattered-light F110W total intensity image at the NICMOS resolution. Right panel: Scattered-light 2 µm polarized fraction map with polarization vectors superimposed.
