Table C.3

Cumulative σ3D and cumulative size data (available on Vizier), used to create Figs. 1, 3, and B.1. We give the median and the uncertainties from the upper and lower 95th interquartile range (2σ) at each step. In the online version, the σ3D values are given for all four cumulative trends that are shown in Fig. B.1 and outlined in Appendix B.1.

Parameter Unit Description
age_step Myr The motions/positions of the stellar members of each next youngest cluster were systematically incorporated at each age-step (thus, age ≥ age_step)
median_sig3D km s−1 Median cumulative σ3D at each age-step
e_lo95_sig3D km s−1 Lower error determined from the 95th percentile
e_up95_sig3D km s−1 Upper error determined from the 95th percentile
median_size pc Median cumulative size at each age-step
e_lo95_size pc Lower error determined from the 95th percentile
e_up95_size pc Upper error determined from the 95th percentile

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.
