Notes. Full Table 3 is available at the CDS (Table A.1). Similar tables are available for other variable stars. A portion of the table is given here to show the general style and form of the resulting data.
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.
