Members of NGC 2516 found with a simple non-probabilistic method (green) and shown in the parameter space explored in this work. Simulated field stars found with the same selection as used for finding the members are shown in blue. Black contours show the likelihood for the position of cluster members predicted by a simulation of a dissolving open cluster. Contours are log-spaced. Top row: XY Galactic plane, proper motions space, colour-magnitude diagram. Middle row: Position along the main axis of the tidal tails (D) and density of stars along this line, two projected proper motions, v projected motion as a function of distance from the cluster. Bottom row: Position on the sky, radial velocity as a function of distance from the cluster, and v projected motion as a function of distance from the cluster.
