Synthetic total intensity images from our radiative transfer model #1 considering a MRN-like power-law grain size distribution with a_min = 0.01 μm and a_max = 1000 μm. The left panel shows the theoretical Stokes I image convolved with a Gaussian PSF with FWHM of 0.̋04 (at 107 pc distance). The middle and right panels show the theoretical model image at 70° processed together with the raw DBI data by the different PCA methods as described in Sect. 2.3. The central 0.̋18 of the image are masked to mimic the effect of the coronagraph on the observations. The units are arbitrary, but the dynamical range of the color bar is taken the same as in Fig. 3.
