Fig. 7.
Top: azimuthal velocities of all the OCs in the full sample (right) and the HQS (left) as a function of RGC. The rotation curve of the gravitational potential in Sect. 4 is superimposed. Bottom: median azimuthal velocities in bins of RGC. We also superimpose the unified rotation curve computed by Sofue (2020) and the non-axisymmetric model by Martinez-Medina et al. (2019).
