The radial velocity corrected to the galactic center vgsr (cz in km/s) is obtained by a correction of the motion of the Sun with respect to the local standard of rest (LSR) and a correction of the LSR motion with respect to the galactic center. The resulting correction is: vgsr = v + 232 sin(al2) cos(ab2) + 9 cos(al2) cos(ab2) + 7 sin (ab2) Where al2 and ab2 are the Galactic coordinates (longitude and latitude) and v is the radial (cz) velocity in km/s given as parameter v . ...

When both fits are performed on a simulated image of either kind, the value of the likelihood function is very effective in choosing the ``right'' model down to typical magnitudes of or with a single-orbit WFPC exposure, and about one magnitude fainter with the expected parameters for WFPC 2 observations (see Table 1). Six orbits are required to reach one magnitude fainter with either camera.) ...

Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
