Hydrogen column density (NH) estimated from OSIRIS data cube. Contours indicate the isophots estimated from the rest-frame H2 1−0 S(1) wavelength. No estimate of NH is available toward the core of object 1 (SE) because no hydrogen molecular lines are detected. Only objects 1 and 3 are covered due to the limited FOV. We obtained NH on the order of 1025.5 toward the core of object 3, possibly explaining the X-ray weakness.
