Fig. 7

Left panel: histogram of proper motions parallel to the Galactic plane. Middle panel: histogram of proper motions vertical to the Galactic plane. Right panel: histogram of the 2-dimensional proper motions located in the north-east-segment of the proper motion diagram. The histogram was fitted with a Gaussian function and a 2σ cut was used as the selection criterion for cluster membership (dash-dotted lines in all three panels).
