Velocity-dispersion profiles with error bars. Different symbols indicate different methods of calculation. M2, M4, and M6 are the profiles computed with pPXF, fitting only the first 2, 4, or 6 moments, respectively. The squares denote the profile calculated with the nonparametric method. The triangles are from outer kinematic data, and the dotted vertical line denotes the core radius at 16.8′′ (Harris 1996).
