Overlay plot of the F200W PSF-subtracted image (background image with colour bar) and the [O III] λ5007 map (white contour). The emission in the PSF-subtracted F200W image largely overlaps with the [O III] λ5007 line map, indicating that the continuum and line emission originate from the same objects, i.e. the quasar host and the close companion. The marked scale of 0$\stackrel{″}{.}$6 corresponds to a physical scale of 3.2 kpc at the redshift of the quasar.
