Abstract
The distribution anisotropy in systems of globular clusters (GCs) in satellite galaxies of the Milky Way is considered using the inertia tensor. The statistical significance of the results is estimated by repeating this analysis for random catalogs. This method reproduces a known planar structure in the distribution of satellite galaxies; however, the significance of this structure is slightly lower than that for other methods used in the literature. For the GCs at distances 2 < R < 10 kpc, the structure is coplanar with the galactic plane. At large distances, the structure orientation is close to the orientations of the satellite galaxies, i.e., is perpendicular to the Galaxy plane. The probability of stochastic realization of such distribution is 1.7%. The GC distribution anisotropy is also measured without the GCs belonging to the Sagittarius tidal stream. Measurements show that the effect of the stream on the GC perturbation is weak.
