Fig. 1
PCA reduced image of the IRDIS K1 filter. The image has a software mask of radii 
, equal to the IWA of our observations. The bright glow at the edge of the mask at PA 0° is an artefact. The dark region at 
and PA ~18° corresponds to a dip in the disk bright inner rim. The white line contours the S/N = 30 region in the K1 image to highlight the disk morphology (see Sect. 5.2).
