Left panel: symmetrized, mid-infrared S⁴G luminosity profile and thin/thick disc decomposition of the 0.08 r₂₅–0.69 r₂₅ (0.8–7.3 kpc) axial range of ESO 533-4 (the one covered by the IFU). The horizontal solid lines indicate the height, z_s above which 90% of the light comes from the thick disc. Middle panel: image of the observed field made by collapsing the spectra. Right panel: velocity field of ESO 533-4 after the subtraction of the recession velocity. The horizontal axis indicates the axial distance to the galaxy centre and the vertical axis indicates the distance from the mid-plane.
