Figure 1: Computed broad-band SED for 1E 1740.7-2942 for a dominant X-ray corona (thick solid line) and a dominant X-ray jet (thick long-dashed line) (see Table 2). Data points and observational upper-limits are also shown. Note that radio constraints are violated for the dominant X-ray jet case. We note that dips at 100 MeV and few GeV are due to photon-photon absorption in the corona and the disk photon fields respectively. At the radio band, the core luminosity at the adopted distance is shown. The slope at this range is similar to that observed (not shown explicitly; see Fender 2001, and references therein). At X-rays/soft gamma-rays, RXTE and INTEGRAL data are plotted (Del Santo et al. 2005). At high-energy gamma-rays, two upper-limits are shown: one from the spectrum of the source 3EG J1744-3011 (EGRET 1), as absolute upper-limit (Hartman et al. 1999), and the other obtained from the sensitivity limits of EGRET (EGRET 2) in the region (Hartman et al. 1999). The diffuse emission flux at 100 GeV observed by HESS in the direction of the source is shown as an upper-limit (Aharonian et al. 2006).
