Velocity dispersion profile, obtained using circular bins around Sgr A*. The green rectangles are the data points from the full data cube, red circle points are from the cleaned data cube. The large discrepancy at r∼ 4^′′ is due to the influence of the star IRS 7 on the green point. Blue diamonds are obtained from single bright stars in the outer fields. Orange triangles are proper motion data from Schödel et al. (2009).
