Notes.

(a)

Only for the HST data.

(b)

Softness computed as per Urquhart & Soria (2016), but only for XMM-Newton and Chandra observations. M, S, and T refer to the net count rates in the 0.3−1.1 keV, 1.1−2.5 keV, and 0.3−10 keV, respectively.

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.
