Galactocentric coordinate time evolution for the star cluster aggregates. Darker lines are for integrations forward in time (i.e., t > 0), while lighter lines are for backward integrations (i.e., t < 0). The present-day positions are at t = 0. Initial conditions were sampled 500 times to account for errors in the mean distance and vLOS, and are shown by thin lines. The thicker solid lines are the median (of those multiple extractions) orbits.
