Nine time-snapshots showing the relative motions of the subregions in vs from −6.8 to 6.8 Myr. This projection represents a face-on view of Orion as viewed from the Sun. The x-axis of the coordinate system points toward (l, b) = (206.038° , − 21.945° ). This is the average position of the cluster Orion X (Chen et al. 2020). Its extent is shown by the red disk in the center with a gray dashed outline. The 14 subregions are shown as filled circles (colored as in Fig. 1) and labeled in the last panel (for Orion A only head and tail are indicated). The symbol sizes are scaled with distance (along the 3rd axis) and are normalized relative to the gray-dashed open circle given in the lower-left corner of central panel (circle size normalized for Orion X); larger points are in-front and smaller points in the back of Orion X, to give an impression of depth. The symbol sizes are scaled for each projection individually and are not comparable between Figs. 7–9. See text for more information. A movie version is available online. See also Fig. 10 for an interactive version.
