X-ray spectrum

Given the low count rate, the background begins to dominate above 2.5 keV. The same models as used for the hot spot were tried for the jet (Tab. 2). The Raymond-Smith thermal models provide a poor fit to the spectrum, even when the metal abundance is a free parameter. An absorbed power-law model provides an excellent description of the spectrum of the jet (Fig. 7). The absorbing column density ($N_{\rm H}$ = 5.8 $^{+6.8}_{-5.6}$ $\times$ 10$^{20}$ atoms cm$^{-2}$) and photon index ($\Gamma$ = 1.94 $^{+0.43}_{-0.49}$) are similar to those found for the hot spot. Again we conclude that most of the absorption occurs in the interstellar medium of our Galaxy. The unabsorbed 2 - 10 keV flux and luminosity of the jet are 2.5 $\times$ 10$^{-14}$ erg cm$^{-2}$ s$^{-1}$ and 1.4 $\times$ 10$^{41}$ erg s$^{-1}$, respectively.
