Synthetic Q_φ (top left) and U_φ (bottom left) polarized intensity images and the radially collapsed surface brightness from the radiative transfer model (top right) and the IRDIS J-band image (bottom right). The inset of the synthetic Q_φ image shows the PSF core of the J-band observation. The MCMax3D radiative transfer model has been constructed to qualitatively reproduce shadow features A, B, and D. Both images have been scaled with the squared distance from each pixel to the star and are shown on a linear color stretch with the U_φ color stretch 100 times harder than the Q_φ stretch. The 80 mas inner working angle of the coronagraph of the J-band observation has been masked out. The red dashed line in the top right figure shows the same radiative transfer model but without the warped disk region (zone 2). The vertically dashed lines show the locations of the surface brightness minima of shadow features A, B, and C. The error bars of the integrated surface brightness show 1σ of the corresponding position angle bin in the U_φ image.
