The ¹²CO SLEDs for the three kinematic components seen within the ¹²CO spectra (from the left-hand to right-hand side for the components at X, Y and Z at ∼−180, 0 and +200 km s⁻¹, respectively). We overplot on each of these a scaled version of the best-fitting LVG model from the combined SLED. This shows that two components, X and Z, also peak at around J_upper∼ 6, while component Y appears to peak slightly lower, J_upper∼ 4, suggesting that there may also be temperature differences between the kinematic sub-components within the galaxy. Interestingly, component Y also appears to contain the bulk of the cold gas as traced by ¹²CO(1–0) compared to either X or Z.
