Notes. EXP indicates the exposure time in ks of each observation (for INTEGRAL, it is given separately for ISGRI and JEM-X2 in parentheses), NH the absorption column density in units of 1022 cm-2, and Γ the power-law photon index of the X-ray spectrum. For INTEGRAL, an exponential cutoff energy was introduced in the fit (energy fixed at 20 keV). is the observed flux and is given in the 0.5−10 keV energy band for Swift /XRT, and in the 3−20 keV energy band for the RXTE /PCA and INTEGRAL /ISGRI+JEM-X2 in units of 10-10   erg/s/cm2.

(a)

This Swift /XRT observation was carried out in WT mode.

(b)

3σ upper limit.

(c)

In these cases this value is C-stat/d.o.f.

(d)

Observations used for the Galactic diffuse emission estimation.

(e)

These are 3σ upper limits on the source X-ray flux (3–20 keV) estimated from the JEM-X2 mosaics.

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.
