Upper panel: three partially overlapped in time 0.5–10 keV (Chandra and XMM-Newton) and 13–200 keV (INTEGRAL) observations. Spectral fits consist of the sum of a BB and a PL (black: Chandra data of Jan. 25, 2009; blue: Chandra data of Jan. 29, 2009; red: XMM-Newton data of Feb. 03, 2009. The same color code applies to the three INTEGRAL observations). Lower panel: the same as the left panel except that count spectra and models are plotted here. Fit residuals are shown in the bottom panel.
