$\begin{figure} \par\includegraphics[height=8.5cm,angle=-90]{0674fig1.ps} \end{figure}$ Figure 1: Contour plot for an absorbed cut-off power law applied to the combined Swift/XRT, INTEGRAL JEM-X1, and IBIS/ISGRI data obtained in December 2006. The contours show the allowed range for the photon index and the cut-off energy at the 1, 2 and 3 sigma level. No cut-off is required by the data.

$\begin{figure} \par\includegraphics[height=8.5cm,angle=-90]{0674fig2.ps} \end{figure}$ Figure 2: Combined spectrum of all Swift/XRT, INTEGRAL JEM-X1, and IBIS/ISGRI data obtained between November 2004 and June 2007. The absorbed cut-off power law fit results in $N_{\rm H} = (1.24 \pm 0.05)~\times~~10^{22}~\rm cm^{-2}$ , photon index $\Gamma = 1.52 \pm 0.05$ , and cut-off energy $E_{\rm c} = 72 {+21 \atop -14}~\rm keV$ for a $\chi ^2_{268} = 0.99$ .

The ratio between the data and the model shows the soft excess at energies below 1 keV, the iron K $\alpha$ line, the significant cut-off at high energies, but no trace of a reflection component.

In addition, 2MASS measurements (J, H, and Ks) and radio data (6 cm and 20 cm) have been added. Data have been corrected for Galactic hydrogen column density, but not for intrinsic absorption.
