Charts for the 18 bright stars described in the text color-coded by ID and with symbol size representing a G₃′ magnitude scale. Left: Current positions. Center: Backtraced positions using the Gaia DR3 proper motions for 0.61 Ma ago, with empty circles used for the current positions and lines joining the backtraced and current positions. Right: Same as the previous panel for 0.88 Ma ago selecting the proper motions within 2.5 sigmas of the measured values that minimize the average mean separation between pairs.
