Three different bar positions for the model gSa (SPH simulation, T = 200 Myr). Top panel: the bar is perpendicular to the major axis, middle panel: intermediate position and bottom panel: parallel to the major axis. The first column is the moment0 map, second column the moment1 map superposed with the isovelocity contours and the third column the comparison between the expected RCs shown as a continuous line and the measured rotational velocities derived using rotcur (black points).
