Notes. Uncertainties and upper limits are at the 90% confidence level. Numbers without error bars were held fixed at the values listed.

(a)

Epoch for data grouping.

(b)

MJD−55 000.

(c)

Total background corrected PCA counts between 7 and 15 keV, in multiples of 105.

(d)

Absorbed flux, in units of 10-2 photons s-1 cm-2. F1 and F2 cover the energy bands 10–20 keV and 7–15 keV, respectively. In epoch VI, the 10–20 keV band is not fully covered by the data and no flux value can be listed.

(e)

In units of 1022 cm-2.

(f)

In units of keV.

(g)

In units of 10-4 photons s-1 cm-2. The centroid energy has been fixed to 6.4 keV, and the width to 10-4 keV.

(h)

In units of eV.

(i)

cPCA, cISGRI and cXRT are defined as the cross calibration and normalization constants for PCA, ISGRI, and XRT, respectively.

(j)

In multiples of 10-2.

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.
