Normalized cumulative distribution function of flare energies for Class III and Class II stars. In the range of energies above the cutoff value Ecut = 2 × 1035 erg (vertical segment), the two distributions are compatible with a power-law with α − 1 = 1.4 ± 0.4; for low counts the distributions flatten, most likely because the detection of low-counts flares is incomplete.
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.
