Notes. The table includes data for stars in the magnitude range 20.16 < mF438W < 22.36 from the two intermediate fields (F4 and F5) and the three outer fields (F1, F2, and F3) examined in this paper, along with the central field analysed in Bellini et al. (2017c). Ratios obtained solely from the counts of classified stars are reported within parentheses.
values from Bellini et al. (2017c).
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.
