Results of the kinematic modelling carried out with KinMS. Left: Surface brightness distribution and line-of-sight velocity field of the CO(2−1) emission for the low- (bottom) and high-resolution (top) data set, respectively. Contours correspond to the best-fit model. Right: Position-velocity diagram along the kinematic major axis. The model includes circular rotation with radial motions, which dominate the bulk molecular gas kinematics from 1.3 kpc down to the black hole SOI.
