Two-dimensional host galaxy fitting results. We used GALFIT on wavelength-average PSF-subtracted images to model the host galaxy’s profile. From left to right, the subpanels display: (a) the wavelength-average PSF-subtracted image, (b) the best-fit Sérsic profile, and (c) the corresponding residual image. The green stars mark the quasar positions. The north is up and the east to the left. We found that J1217+0234 and F2M1106 did not provide well-constrained fits.
