Comparison of snapshots taken from a 64 000-star single cluster (64kW08, left column) and a merger of two 32 000-star clusters (32kmerge7+7, right column). The rows correspond to different times in units of the single-star cluster half-mass relaxation time. In the plots each point represents a star in the plane of the sky. The x- and y-axis are in units of the projected half-mass radius. It is hard to visually tell the difference between the two snapshots. The bottom panel corresponds to the age-range of the snapshots used for the machine-learning study.
