Gas line-of-sight velocity field with the stellar surface brightness overplotted as contours for the model-A dwarf system during the minor merger shown in Fig. 1 at t = 2 Gyr, but now for an inclination angle of i = 72.6 deg from face-on. The kinematic axis for the gas (solid line) and the major axis of the surface brightness distribution (dotted line) are misaligned. The fitted profiles to the stellar and gas (dashed line) distributions have similar orientations, and this is because they are dominated by the behaviour in the central regions.
