Polarized-light Q_T images (left column) and intensity I images (right column) of HD 163296, HD 150193, and HD 141569A. North is up, east is to the left. The central white area denotes the saturated pixels, which are not included in the analysis. All images are scaled by r² to compensate for stellar dilution. This enhances the brightness of the companion and of all outer speckles. All Q_T images are shown with the same linear scale, whereas the scale of the I images is arbitrary to highlight each PSF.
