Left panel: velocity map of H₂ 1−0 S(1) (left) and first-moment map of CO(3−2) (right). Dotted lines mark the position-velocity cut shown in the right panel. Mid panel: integrated line profiles of CO(3−2) (red) and H₂ 1−0 S(1) (black) for each SGMC. Blue spectra show the CO(3−2) lines convolved to the spectral resolution of SINFONI. Black bars correspond to 5 × 10^-16 erg s^-1 cm^-2 Å^-1 for H₂ 1−0 S(1)  and red bars to 1.5 Jy for CO(3−2), for all SGMCs. Offsets between the black and blue spectra indicate variations in the CO-to-H₂ ratio between velocity components. Right panel: H₂ 1−0 S(1) position-velocity diagram of SGMC 2 (H11), with CO(3−2) emission shown as contours in steps of 0.02 Jy beam^-1 starting at 0.03 Jy beam^-1.
