Notes. The SigMA identification numbers, the traditional region each group belongs to, the group names and the number of member stars of each group are taken from Ratzenböck et al. (2023b). Cluster ages are from Ratzenböck et al. (2023a). Positions (α, δ), parallaxes (π) and proper motions ( $μ_{α}^{*}$ $Mathematical equation: $ \mu^{*}_{\alpha} $$ , μ_δ) are from Ratzenböck et al. (2023b) and Ratzenboeck et al. (2023). See Sect. 2.2.1 for an explanation of how the group radii R were determined. π_trace are the parallax values from Ratzenböck et al. (2023b) with larger margins of error that incorporate the respective group radius (see Sect. 2.2.1). See Sect. 2.2.2 for an explanation of how the radial velocities v_rad were obtained.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
