Notes.

^(a)

We use the subscript “m” to distinguish the mass fraction of elements other than H and He from Galactic XYZ coordinates.

^(b)

The errors of the last significant digits are given in parentheses.

^(c)

[Fe/H] calculated from Z_m according to Pöhnl & Paunzen (2010).

^(d)

Photometric systems used for the analysis: e.g. Str (Strömgren), pe/ccd stands for photoelectric and CCD data, respectively.

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.
