Map of the masks used in our analysis (left) and [OIII] kinematic maps (middle and right panels). The colours in the first map have no particular meaning but help to differentiate the apertures. A 1D spectrum was extracted from each one, so that a single W₈₀ and V_s (middle and left panels) value is associated with each aperture. V_s is the velocity shift relative to the narrow core of the nuclear [OIII] line. The maps cover the total MUSE FoV (∼1′×1′). W₈₀ and V_s are in km s⁻¹. Letters ‘A’–‘F’, the yellow star, and the solid lines have the same meanings as in Fig. 1.
