Top left: H-band spectra of XID5330 around the [O iii] λ4959, 5007 lines extracted from a region of 1′′× 1′′ centred at the QSO position. The observed spectrum in shown in black and the full fit model is shown in red. Owing to low S/N on the spectra, only a single Gaussian component was used for line fitting. The lower panel shows the residuals of the line fit. Top right: map tracing the Gaussian component in the [O iii] λ5007 profile of XID5330. The white contours show the continuum levels at 50%, 75%, and 95%. Each pixel corresponds to a spatial scale of 0.25′′ (~2.12 kpc). North is up and east is left. The grey circle on the lower left shows the size of PSF. Bottom panel: surface brightness profile of the narrow component of the map in the top right panel compared to the PSF profile. The [O iii] λ5007 emission is extended up to 1.1′′ (~9.5 kpc).
