Three-dimensional distribution of the groups in Orion from Paper I. The groups are color coded by the average age of the stars within them, with red being the youngest; the size of the dot corresponds to the number of stars inside each group. The panels show the traceback and the trace forward look over the −8 and +8 Myr, with 0 Myr corresponding to the present day. Positions of these groups linearly evolved through time, assuming the current velocity. The observer is positioned to the right of the image. An interactive version that allows the change in perspective, with the age slider of up to 12 Myr in either direction, is available online.
