Notes.
The location of the AR on the solar surface at the beginning and the end moment of the observation period.
The area values are taken at the moment when the centre of mass of the AR is at or very close to the visible central meridian.
The thresholds of unsigned magnetograms for the corresponding unsigned binary images are used to isolate magnetically active pixels (Hoeksema et al. 2014) for each AR.
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.
