Notes. The columns are as follows: Nclusters : number of clusters in the paper; Nsources: total number of stars in the paper; f6D: fraction of stars with 6D information; qparallax_over_error: 1st, 50th and 99th quantiles of parallax_over_error; qradial_velocity_error: 1st, 50th and 99th quantiles of radial_velocity_error; median span of all tails in the paper in the Cartesian and sky planes. All the numbers are after giving the 500 pc selection cut and the recommended quality cuts. ‘5D+’ in the technique means that the radial velocity was heavily used, but was not necessary.
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.
