Proper motion maps of YSOs in NGC 2264 N, NGC 2264 S, and Collinder 95. Stars flagged as YSOs via our spectroscopic analysis are marked with an open circle, while YSOs flagged through the Gaia variability catalog are marked with smaller black point. (Stars flagged by both indicators are denoted through a filled in circle/larger black point.) The proper motion of each YSO is shown with an arrow which is color coded according to the direction of motion. The average motion of each cluster or subcluster has been subtracted out (see these values in Table 2), allowing us to observe the plane of sky motion of each YSO within the cluster frame. The center of the cluster is denoted by the intersection point of the dotted two lines. The dotted blue circle denotes the half-mass radius of the identified YSOs in each cluster.
