Notes. The first column corresponds to the [O/H] value, the second to the 
dust-to-gas ratio normalized to the value of 10−2 (see Eq. (2)), the third to the carbon abundance, and the fourth to the oxygen abundance (calculated using the best-fit of Sharda et al. 2023b,a). In the fifth column, we list the most representative objects in each case.
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.
