The authors have mapped the 158 μm fine structure line emission of C+ over a region of ≡30 pc diameter toward the galactic center. They use the kinematic information from the C+ profiles together with a computer model of a turbulent, rotating disk to derive the rotation curve and mass distribution between 2 and 10 pc from the center. The measurements are well fitted by a thin, azimuthally symmetric disk of inclination ≡65° in Keplerian rotation around a central point mass of 6.5±1×106M_sun;. The best overall mass model, including all presently available data, indicates 5 - 6×106M_sun; within 2 pc from IRS 16 and 8 - 15×106M_sun; within 10 pc of IRS 16. The mass to luminosity ratio of the central stellar cluster is 0.5 M_sun;/L_sun; or less, suggesting a large abundance of giants and relatively recent star formation in the center.
