Notes: a Phase zero for the orbital period is MJD 50439.919 (Wen et al. 2000; Levine et al. 2004). b Phase zero for the superorbital period is the maximum of the folded light curve at MJD 59502.1 (Islam et al. 2023). c Observed flux in the 0.3–10 keV energy band in units of ×10−11 erg cm−2 s−1. When no value is provided, the observation yielded insufficient counts to perform spectral analysis.
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.
