Fig. 5


Panel a: Qφ image of DZ Cha in logarithmic scale. The rest of the panels are shown in linear scale and the dynamical range of each image has been adjusted to better show the disc structure. Panel b: Zoom-in of a) with the polarization angle Pθ plotted as grey vectors. Panel c: Ratio of Qφ over the total intensity (I). The central cross indicates the projected major and minor disc axis. Panel d: Uφ image normalized to the maximum value of Qφ. The positive/negative pattern is characteristic of multiple scattering events. In all panels the innermost region () dominated by speckle noise has been masked out; north is up and east is left.
