Sgr A* ``Visual Binaries'': A Direct Measurement of the Galactocentric Distance [PDF]
, 1998 We present a new geometrical method for measuring the distance to the Galactic center (R_0) by solving for the Keplerian orbit of individual stars bound to the black hole associated with the Sgr A* from radial velocity and proper motion measurements.
