Notes.

^(a)

Observation setup: full-frame mode (ff) and photon-counting mode (pc). For XMM-Newton, the filter is given as well.

^(b)

Off-axis angle under which the source was observed.

^(c)

Net counts as used for spectral analysis in the (0.2−10.0) keV band for XMM-Newton and in the (0.3−6.0) keV band for Swift.

^(d)

Radius of the circular source extraction region.

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.
