Fig. 3
Upper left panel: Gunn r-band image of SDSS J215051.73+ 111916.6 obtained at the NTT. Note the double image of the target created by the polarization optics. Field size is 29 × 29′′, north is up and east to the left. The red circle marks the area included in the fit and the green circle an area masked out due to an overlapping target. Upper right panel: PSF image extracted from a field star. Lower left panel: best fit model (core + host galaxy) of the target. Lower right panel: residuals after subtracting the model.
