The synthetic OCs generated over 5 Gyr within 1 kpc with t_dis,O and ﹩{t}_{{\rm{dis}},{\rm{sim}}}﹩ are shown in blue dots and green diamonds, respectively. We show the initial mass at age = 0 for all of the dissolved OCs over the last 5 Gyr, and we show the current mass and age of the surviving OCs. All recorded snapshots from our simulations are shown with orange dots.
