Notes.
Net counts in the full (0.5–7 keV), soft (0.5–2 keV), and hard (2–7 keV) bands, respectively. Errors on the X-ray counts were computed according to Tables 1 and 2 of Gehrels (1986) and correspond to the 1σ level in Gaussian statistics.
The hardness ratio is defined as 
where H and S are the counts in the hard (2.0–7.0 keV) and soft (0.5–2 keV) bands. We calculated errors at the 1σ level for the hardness ratio following the method described in Sect. 1.7.3 of Lyons (1991).
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.
