  2. Overview • Orbit-based Schwarzschild models • Combination of line-of-sight velocities and proper motions • Allows to constrain distance, mass profile

  3. Data • Surface brightness profile from HST+ground • 1556 stars with line-of-sight velocities • Gebhardt et al. (2000) • 704 stars with proper motion velocities • McNamara et al. (2003)

  4. Conclusions • Distance of 10.3+/-0.8 kpc • Total mass inside 0.03 pc is 2700 M • Central density of 107 M/pc3
