Example of emission line maps produced from the fitting of the [O III]λ5007 line using the MUSE ISM cube (Sect. 3.3.1). Shown, from left to right, are the maps for the primary component: velocity field (km s⁻¹), velocity dispersion (km s⁻¹), and flux intensity (erg s⁻¹ cm⁻¹, log scale). The black solid line indicates the major axis of the stellar rotation (Table 4). The dot-dashed square indicates the MEGARA field of view. The contours indicate the central region at high velocity dispersion (see Sect. 4.2.3 for details). Top: maps covering a smaller field of view with respect to the original MUSE mosaic (80″ × 80″, Sect. 2.1) to highlight weak features. The dashed square indicates the selected zoomed-in view in the bottom panels of this figure and for Figs. B.1–B.13. Bottom: zoomed-in area. The dashed line indicates the orientation of the radio jet (Table 1).
