Notes. The values correspond to the best-fit single temperature models in the

^(a)

2−7 keV band;

^(b)

0.5−2 keV band;

^(c)

0.5−7 keV band;

^(d)

~6.0−7.0 keV band; and

^(e)

2−6 keV band. The ACIS values are obtained using CALDB 4.2.0. (e) μ gives the weighted mean of the relative difference between the two measurements in percentages;

^(f)

sig. gives the significance of the relative difference in terms of σ.

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.
