Fig. B.1
Results of the single Gaussian fit to the H2 gas emission line. Upper panel: flux in logarithmic scaling and with respect to the maximum flux. Middle panel: velocity in km s-1. Lower panel: velocity dispersion in km s-1, corrected for the instrumental dispersion (σinstr ≈ 27 km s-1). The coordinates are centred on Sgr A* and along the Galactic plane with a position angle of 31.̊40. The cross marks the position of Sgr A*.
