Radial profile of the Q_ϕ image. The black profile shows the radial profile obtained along a 2.5″ long slice centered on the star in the N–S direction, with PA = 7° and extending along the disk (black-dashed box in the insert). The blue-dotted profile shows the radial profile obtained in the orthogonal direction (E–W, blue-dashed box in the insert). All profiles are normalized to the brightness peak of the disk. The gray area shows the radius of the coronagraph.
