Notes. This table includes data from all three APOGEE observations and Optical MIKE measurements. Associated uncertainties for chemical abundances are presented alongside each measurement. Notice that the APOGEE observations have some flags reported in the text. The uncertainties for our optical measurements are $u_{T_{eff}} = 150 K$ ${u_{{T_{{\rm{eff }}}}}} = 150{\rm{K}}$ , u_{log ɡ} = 0.10 dex; u_{v sin i} = 7 km/s. Typical uncertainties reported for APOGEE are $u_{T_{eff}}$ ${u_{{T_{{\rm{eff }}}}}}$ ~ 140 K and u_{log ɡ} ∼ 0.08 dex.

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.
