Oort particle distributions due to gravitational influence of GCs. The different zones are as follows: Less than 2 pc – inner zone (top panel), from 2 pc to 1000 pc – middle zone (middle panel), and above 1000 pc – outer zone (bottom panel). The solid lines show the particle distribution, and dotted lines show moments of the GC deep passages. The colours represent potentials. The larger green dots represent the results with the N = 50 k Oort cloud number (re-scaled).
