Notes. Phases and cycles are computed with T0 = JD 2456023.533 and P = 35.5496 d. Cycles are counted from the first observed one. The signal-to-noise ratio (S/N) is calculated over the wavelength range 2212.0–2212.3 nm for 2012 and 2013 data, while the range 2208.2–2208.5 nm is used for the 2008 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.
