Line-of-sight velocity dispersion (top panel) and velocity (bottom panel) radial profiles measured along the major axis of NGC 1366 for the total (black filled circles), counter-rotating (blue filled square), and co-rotating (red filled diamonds) stellar components and for the ionized gas component (green open triangles). Error bars smaller than symbols are not shown. The blue and red horizontal lines in the top panel mark the radial bins we adopted for measuring the counter-rotating and corotating components, respectively. The blue and red dashed lines in the bottom panel are a tentative indication of the velocity rotation curves for the counter-rotating and corotating component, respectively.
