Geometric mean of the proper motion dispersion (left) and radius containing 50% of members (right) for the clusters reported in this work, as a function of distance. Clusters are split between those detected in previous works (blue circles) and those newly reported in this work, divided between the high quality (orange squares) and low quality (grey triangles) samples defined in Sect. 7.1. The cuts on cluster parameters to distinguish between bound OCs and unbound moving groups or associations proposed in Cantat-Gaudin & Anders (2020) are shown as a dashed black line.
