Intensity, LOS velocity, and velocity dispersion profiles of the Cartwheel’s bar. Left: intensity map for the inner region of the Cartwheel. The extent of the bar and bulge are shown by ellipses, as in Fig. 2. Right: intensity, LOS velocity, and velocity dispersion profiles along the grey rectangular pseudo-slit shown in the left panel. The vertical dashed black line at the centre signifies the position of the minor axis, whereas those on either side highlight the bar ends.
