Fig. 5
Top: averaged radial profile of the linear degree of polarization for the continuum (blue) and Hα (red) filters as a function of the radial distance in the SE (left, 90°< PA < 157.5°) and NW (right, 270°< PA < 315°) regions. Bottom: corresponding ratios (log scale) in the polarization of both filters. The horizontal dotted line indicates equal polarization in both filters and the vertical dashed line the rough radial position of planet candidate c in the SE region.
