Left: NGC 3941 column density map. The contours are 0.5, 1, 2, 4 × 10²⁰ cm^-2. The ellipse on the bottom-left describes the beam shape. Right: first-moment velocity field. The contours range from 780 to 1080 km s^-1 with 30 km s^-1 steps. The overlaid ellipse describes the model geometry (kinematic centre, position angle, inclination and radius). The ellipse on the bottom-left describes the beam shape.
