Top: observed velocity map of ESO 533-4. Middle and bottom rows: set of velocity maps from models designed to mimic the region shown in Fig. 3. The three columns correspond to: a) a perfectly edge-on galaxy with no counter-rotating material; b) a galaxy 3° away from edge-on with no counter-rotating material; and c) a galaxy 3° away from edge-on with 10% of counter-rotating material in the thick disc. The top row corresponds to models with no dust and the bottom row corresponds to models with some amount of dust (see text). The horizontal lines indicate the height above which ~90% of the light comes from the thick disc.
