The Galactic Center (GC) star cluster is a compact stellar system. The surface brightness distribution at infrared has core radius of about 0.8 pc (Rieke & Lebovsky 1987) when the contribution from bright stars are removed. On the other hand number counts of infrared sources in the high resolution speckle image by Eckart et al. (1993) at 2.2 μm gives 0.15 pc for the core radius of the surface density distribution. At present it is not clear which is more appropriate for the mass distribution.
