Fig. 5


RY Lup disk surface brightness profile measured along the midplane on the IFS intensity image (asterisk line) expressed in mag arcsec−2M, IRDIS intensity image (red dotted line) expressed in mag arcsec−2M, and IRDIS polarimetry image (blue dashed line) expressed in arbitrary units. The grey area represents the separation range masked by the coronagraph. The intensity is normalized to the unsaturated non-coronagraphic PSF intensity peak. The error bars are within 0.1 mag.arcsec−2.
