Notes. The first column is the Gaia DR2 source ID. Columns 2, 5, and 8 are respectively. The columns labelled 5% and 95% are the bounds of corresponding confidence intervals. Columns 11–16 list the parallax (ϖ, plus the 0.029 mas zeropoint offset), total proper motion (μ), and radial velocity (νr) along with their 1-sigma uncertainties. Column 17 is the estimated mass of the star from Fouesneau et al. (in preparation); NA indicates it is missing. The formal 1-sigma uncertainties in the masses are a few percent (systematics are likely to be higher). Those encounter results we consider bogus are marked with the dagger symbol in the final column. These are discussed in the text. Other may also be dubious: quality metrics from Gaia DR2 can be found in Table 3. The full table is available at the CDS and includes all 3379 stars in the filtered sample and reports some columns to a higher numerical precision.

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.
