Notes. The HQS, LQS, and weighted photometric metallicities, respective errors, number of stars used for the calculation (N), and the total weight (W) of the photometric metallicities. The code for the photometric systems is 1 (DG), 2 (DDO), 3 (Friel), 4 (Ca II), 5 (Strömgren), 6 (Caby). The last column indicates the number of studies used to calculate the mean distance from the Sun and the age of the open clusters.

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.
