Velocity field as traced by the lines Hα (top, with respect to barycentric velocity), [N ii] 6584 relative to Hα (middle), and [S ii] 6731 relative to [N ii] 6584 (bottom). We note that the linear color scales are different for all these plots and that the range of the middle plot is asymmetric. The locations of the brighter stars in the field are marked as black circles, further noticeable features are annotated or marked in green or gray on the Hα velocity map.
