Broadband SEDs for the epoch of radio observations (top), roughly the present epoch (middle), and roughly the periastron passage (bottom). For the epoch of radio observations, we show the ATCA data from 2008–2009, and upper-limits in the X-ray flux derived from Benaglia et al. (2006). Dashed lines indicate contributions from synchrotron (brown), IC (cyan), relativistic Bremsstrahlung (olive), and p-p (green); the filled red curve is the total emission. We show instrument sensitivity curves for 1-Ms NuSTAR (gray), 4-yr Fermi (dark gray), and 50-h CTA (black).
