Extracted quasar spectrum within a 0$\stackrel{″}{.}$35 aperture centered on the spaxel with the highest integrated flux. The observed spectrum, shown in black, is aptly fit by the PyQSOFit model, shown in orange. Broad Hβ and Hγ are modelled using three and two broad Gaussian components (pink lines, individual Gaussians are shown in purple) with FWHM > 1200 km/s, and one Gaussian component with FWHM < 1200 km/s to trace narrow components (green line). The [O III] λλ4959,5007 emission lines are modelled with one broad and one narrow component. No narrow [O III] λλ4959,5007 components are detected, whereas a strong contribution from Fe II emission (blue line) is evident (Park et al. 2022). The lower panel shows fit residuals.
