Left panel: map of the Hα+[OIII] emission from NIRSpec-IFU; the masks used to extract the spectra of the subregions discussed in Sect. 4.1 and Sect. 4.2 are over-imposed. The relative spectra (covering the wavelengths around Hβ, [[O III]λλ4959, 5007] and Hα) are shown in the right panels. All the other IFU masks used in this work (and shown in Fig. 2 and 6) are included for comparison as white contours (with black labels).
