Comparison of the [Cii]λ158μm and H₂ (1−0) S(3) line profiles in 3C 326N. All lines have been arbitrarily scaled (maximum line flux of 1) to facilitate a direct comparison. Top panel: comparison between [Cii] and the integrated H₂ 1−0S(3) 1.9576μm line profile (green dashed line). Central panel: total integrated H₂ 1−0S(3) line and decomposition of the H₂ line emission originating from the northern disk hemisphere (red solid line) and the southern hemisphere (solid blue line), respectively. Bottom panel: the integrated [Cii] line profile (solid black line), and H₂ line extracted from the northern hemisphere (solid red line).
