Notes. 

(a)

ΔvR is in the sense FORS2-H10.

(b)

HP1: the difference listed is with respect to the heliocentric velocity given by Barbuy et al. (2006), which we give in lieu of the Harris catalog value. It appears the catalog lists the uncorrected observed value.

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.
