Position velocity plot of the H₂ 1–0 S(1) line extracted along the major axis of the inner disk. Contour levels are –3, –2, 2, 3, 5, 7,9, and 12σ. The black dashed line shows the rotation curve predicted from the stellar photometry, while the fine dashed line shows the contribution of the SMBH to the rotation. The solid line is the total rotation curve derived from the two. In the centre at velocities ≳+220 km s^-1, we identify a component of H₂ deviating from the predicted rotation curve (see Sect. 3.2 for further details).
