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 (σ_instr ≈ 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*.
