Left: normalized azimuthal profiles of the ring from all three coronographic and one noncoronographic epochs, averaged over radii of ~0.1–0.15 arcsec, with a vertical offset of 0.4 between profiles. Right: normalized azimuthal profiles of the outer disk from all three coronographic epochs, averaged over radii of ~0.23–0.8 arcsec, witha vertical offset of 0.4 between profiles. In both panels, the sequence of curves from bottom to top is the same as in the legend.
