Comparison of the total intensity image (panel a) and the Q_φ image (panel e) with the models of scattered light (panel b) and scattered polarized light (panel f). Panels c and g: models after convolution with the instrumental PSF and post-processing. Panels d and h: residual images obtained after subtracting the model images from the total intensity image and the Q_φ image. White crosses indicate the position of the star. Color bars show flux in counts per pixel.
