Fig. 2

Two examples of the QSO-host deblending process for SDSS i band images. The PSF was constructed from a bright nearby star in the field. A best-fitting Sersić surface brightness model plus a PSF for the nucleus was obtained with GALFIT and subtracted from the original SDSS image to highlight the residuals. The host galaxy is recovered after subtracting the best-fit PSF component from the original image with nucleus-to-host ratios of ~3.5 and ~2.2 for SDSS J0057 + 1446 and SDSS J0836 + 4426, respectively.
