Fig. 4
Constant surface brightness (SB) profiles and residuals for FGS28. The contours represents SB from 21 to 27 mag arcsec-2, separated by 1 mag arcsec-2. In the contour images, the blue line is equivalent to 50 kpc at the distance of the FGS28. In the residual images, the ellipse represent the 25 mag arcsec-2 of the BGGs (see text for details).
