Notes. Best-fit parameters of the spectrum observed by XMM-Newton (RGS in the 0.6−2.0 keV energy band and EPIC-pn in the 1.4−10 keV range) on March 26, 2016 (central column), and of the simultaneous spectrum observed by XMM-Newton and INTEGRAL (JEM-X in the 5−25 keV, and ISGRI in the 20–150 keV band; rightmost column). Fluxes are unabsorbed, given in units of 10-9 erg cm-2 s-1, and evaluated in the 0.5−10 keV for the XMM spectrum and the 0.5−100 keV energy band for the XMM-IGR spectrum. Uncertainties are quoted at the 90% confidence level.
