Notes. Mid-exposure phases were calculated using the ephemeris of Tramper et al. (2016), exposure times correspond to on-axis values (for pn if XMM-Newton). The XMM-Newton count rates correspond to the sum of MOS1, MOS2, and pn values. both ^* and ^- cases were used for spectral fitting (see Sect. 4 and Table 6). The Swift data were acquired by request of the PIs Y. Sugawara and A. M. T. Pollock.

^(*)

Observation leading to a good spectrum;

^(–)

observation leading to a rough spectrum with about 80–150 raw counts for the source;

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.
