Caption: Figure 8.

Velocity dispersion profiles along the tangential and radial components in the plane of the sky (from this work) and along the LOS (from Bianchini et al. 2013), compared to our best-fit axisymmetric rotating model (in green). Note that the blue and red lines are barely distinguishable from the green line.
