Comparison of the Orbital Properties of the Milky Way Globular Clusters
  from the Data of the Gaia DR2 and EDR3 Catalogs
  We provide new values of the orbital parameters of 152 globular clusters,
which are calculated using the new mean proper motions obtained from the Gaia
EDR3 catalog data. The orbits were integrated 5 Gyr back in an axisymmetric
three-component potential with a spherical bulge, disk component, and spherical
dark halo in the Navarro-Frenk-White form, which we refined using the rotation
curve of objects with large galactocentric distances up to 200 kpc. The
obtained orbital parameters were compared with the orbital parameters of the
same globular clusters calculated earlier in the same gravitational potential
using proper motions from the Gaia DR2 catalog data. The objects whose orbits
underwent significant changes were identified.
