Fig. 5


Mean normalized profile of the r-band PSF model profiles for two bins of seeing (top-left); mean profile of the g- and r-band profiles for a specific seeing bin (bottom-left) and the r-band surface brightness map of a typical stellar ghost (right). The standard deviation of each profile is shaded. The surface brightness scale in mag arcsec-2 is given to the right. The map is blurred with a Gaussian (sigma = 0.55′′) to enhance the faint regions. The vertical black lines in the plots to the left indicate the radii with sharp breaks in the profiles. Their positions on the surface brightness map are indicated by the white circles.
