Ionised gas velocity maps of the Teacup from the fit of the stellar continuum-subtracted, Voronoi-binned data cube (see Sect. 2.2). [O III] velocity, obtained as the first-order moment of velocity of the total modelled line profile (left panel), as well as velocity of the first (middle panel) and second plus third Gaussian components (first-order moment of velocity of their summed profile; right panel) employed for the line profile modelling. In the left panel we report the contours of [O III] flux (from Fig. 3, top-left panel) to allow for an easier visual comparison between the Voronoi-binned velocity field and the morphology of the ionised gas emission.
