Notes. V stands for the velocity of the spectral feature, 
the average flux density during the observation period, R the relative flare amplitude calculated as (Smax − Smin)/(Smin), PLS the period estimation using an L−S periodogram, PAoV the period estimation using AoV, FWHM the timescale of the flare, Rrd the rise-to-decay ratio of the flare, and t the time delay calculated with the DCF.
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.
