Left: top and middle panel: histograms and proper motion distributions of μ_αcosδ and μ_δ of Danks 1, Danks 2 and comparison field. Left: bottom panel: RV distributions of Danks 1, Danks 2 and DB132. The solid lines represent the best Gaussian fit, outliers are labelled. Right: radial velocities for our spectroscopic targets as a function of distance from the Danks 1 (top), Danks 2 (middle) and DBS 132 (bottom) cluster centres. The horizontal lines represent the dispersion of the Gaussian fit (see text). The adopted cluster diameter is shown by the vertical line. The error bars represent the random error in determining the RV for each star.
