Fig. 3
Hα line of sight velocity field with Hα SB contours from Fig. 1. A background [O ii] λ3727 emitter at z = 0.78 coincident with Hα contaminated the fit towards the north and hence the respective region is masked (black circle). We spatially smoothed the data cube with a top hat filter (r = 1′′) to enhance the signal to noise for the fit.
