Galactic Orbits of Globular Clusters in the Region of the Galactic Bulge
  Galactic orbits have been constructed over long time intervals for ten
globular clusters located near the Galactic center. A model with an axially
symmetric gravitational potential for the Galaxy was initially applied, after
which a non-axially symmetric potential corresponding to the central bar was
added. Variations in the trajectories of all these globular clusters in the XY
plane due to the influence of the bar were detected. These were greatest for
the cluster Terzan 4 in the meridional (RZ) plane. The globular clusters Terzan
1, Terzan 2, Terzan 4, Terzan 9, NGC 6522, and NGC 6558 always remained within
the Galactic bulge, no farther than 4 kpc from the Galactic center.
