Notes. Uncertainties are 1σ values. (a)Gaia Collaboration (2016, 2021), distances and uncertainties correspond to inverted EDR3 parallaxes. (b) Alternative solution, adopting the Gaia distance instead of the spectroscopic distance. See Sect. 5 for details.

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.
