Notes. This table will be available in its entirety in machine-readable form at the CDS. For each star, we provide the Gaia-DR2 identifier, position, proper motion and parallax (not corrected for zero-point offset) from the Gaia-DR2 catalogue, RUWE value, membership probability, RV with reference, distance derived from Bayesian inference, UVW spatial velocity, molecular cloud, and SED class. References for radial velocities are: (1) Sacco et al. (2017), (2) Nguyen et al. (2012), (3) Guenther et al. (2007), and (4) Joergens & Guenther (2001).
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.
