Notes. Information in Cols. 2–7 comes from Cantat-Gaudin et al. (2020) and the following: Bell et al. (2013) age of NGC 2244 and NGC 6530; Venuti et al. (2018) age of NGC 2264; Franciosini et al. (2022) age of γ Velorum; Damiani et al. (2017b) age of Trumpler 14; Grasser et al. (2021) age of ρ Oph; Galli et al. (2021) age of Cha I. Columns 8 and 9 list the number of spectra and targets, while the average [Fe/H] and standard deviation are given in Col. 10. In most cases [Fe/H] was derived in this paper as described in the text. Metallicity for NGC 3293, NGC 3766, and NGC 6649 was instead taken from Bragaglia et al. (2022). Clusters with an ‘a’ and/or ‘c’ superscript also have spectra retrieved from the archive or have been observed as calibration targets.
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.
