Notes. For XMM-Newton, we provide the EPIC-pn values in the table.

(a)

Modified Julian date relative to the start of the observation.

(b)

Where applicable, the exposure times are free from periods of high background activity, but they are uncorrected for vignetting and CCD dead time.

(c)

Total X-ray photon events detected in the 0.3–2.0 keV energy band.

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.
