Hβ (left panel) and Hα (right panel) spectral region fit in 5 × 5 NIRSpec spaxels centred on the QSO position. In the upper panels, the data are shown in black, and the best-fitting broad line region components (e.g. Hβ, Hα, and FeII) are shown in blue, the narrow line region/host galaxy components (i.e. Hβ, [OIII], Hα, [NII], and [SII]) are shown in green, and the total flux is presented in red. The lower panels show the fit residuals.
