Rotation of the MaNGA galaxy M-8274-12703. Panel a: Line-of-sight velocity field in sky coordinates (pixel). The velocity value is colour-coded. The circle shows the kinematic centre of the galaxy, the line indicates the position of the major kinematic axis of the galaxy, and the ellipse is its optical radius. Panel b: Rotation curve (points) and its fit (line) within the optical radius.
