Response-corrected Chandra/ACIS-I X-ray spectrum of the FRII nucleus (XID189) and best-fit model (in red). By fixing the photon index to 1.8, a best-fit column density of cm⁻² and an intrinsic deabsorbed luminosity in the 2–10 keV rest-frame of L_X = 1.3 × 10⁴⁴ erg s⁻¹ are obtained, which qualify XID189 as a Compton-thick QSO. The spectrum has been rebinned for display purposes. The inset shows a 30″ × 30″ cutout of the 0.5–7 keV Chandra raw image around the source. VLA radio contours at 1.4 GHz are overlaid in blue (with a geometric progression starting at 30 μJy beam⁻¹).
