  • 3 X-ray counterparts seen with Swift within IBIS error
  • Only one detected at > 3 keV => favoured as counterpart
  • R~16.6 and B~17.9 (USNO-A2.0), and J ~15.8, H ~14.7 (2MASX)
  • Galaxy in NED
  • X-ray spectra => simple power law with Γ ~1.7-2.0
  • Average spectrum <=> intrinsic absorption (NH~0.2 x1022 cm-2) and Γ ~2.2
Parisi et al. 2010: ATel 2839 see also Masetti et al. 2012
  • Optical spectroscopy of the suggested X-ray counterpart
  • Optical spectrum => broad Hα and Hβ emission lines at z = 0.095, relatively flat continuum +no narrow emission lines
  • Source is a Seyfert 1 AGN, confirm the association of the (Optical) X-ray and IGR sources.
  • MBH=2.4 x 107 Msun (Masetti et al. 2012)
