Ks image of the field available here
Magnitudes : J=13.18, H=12.02, Ks=10.94, B=19.3, R=14.9 and I=13.8
Likely redshift z=0.035 (Masetti et al. 2004, A&A)
Likely distance 166 Mpc (Masetti et al. 2004, A&A)
>Combi et al. 2006 :
  • confirm Seyfert 1 nature
  • not resolved at radio freq.
  • radio spectral index -0.75=> optically thin synchrotron emission from jet
  • redshift z=0.0034
  • typical Seyfert 1 although brighter at high (X-ray) energies
Panessa et al. 2008 :
  • XMM+INTEGRAL joint spectral analysis
  • Absorbed cut-off power law with narrow emission lines at 6.4 and 6.67 keV
Rodriguez et al. 2011 ATel 3125:
  • XMM position compatible with all previously suggested counterparts
  • 2-sigma level compatibility with 1RXS J180245.5-145432.
