Orbits of 152 Globular Clusters of the Milky Way Galaxy Constructed from
  the Gaia DR2 data
  We present orbits and their properties for 152 globular clusters of the Milky
Way galaxy obtained using average Gaia DR2 proper motions and other astrometric
data from the list of Vasiliev (2019). For orbit integrating we have used the
axisymmetric model of the Galactic potential based on the Navarro-Frenk-White
dark halo, and modified by Bajkova and Bobylev (2016) using circular velocities
of Galactic objects in wide region of Galactocentric distances (up to 200 kpc)
from Bhattacharjee et.al. (2014) catalog. Based on the analysis of the obtained
orbits, we have modified the composition of the subsystems of globular clusters
presented in Massari et. al. (2019).
