Notes.
The period on t = 56
716 (MJD) is computed using
with P0,
Ṗ0,
the period, period derivative and
period second derivative given in the literature, t0 the
reference epoch in the literature. Errors are propagated until t = 56 716 (MJD)
thanks to dP2 = ∑
(∂P/∂p)2
dp2.
The errors are the 90% confidence interval (see left panel of Fig. B.2).
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.
