Normalized PSFs of HD 183143 for the V-band (top) and the N_I-band (bottom) with the color scale reduced by a factor of 100 for the central peak within r < 20 pixels. Marked PSF features are the speckle ring near the AO control radius (r), strong fixed speckles from the AO system (s), two telescope M2 spider features (t), and the CCD frame transfer trail of the PSF peak (c). The dashed rings illustrate the location of the azimuthal cuts shown in Fig. 9.
