Overlay of the CO(1–0), CO(2–1), and CO(3–2) spectra observed in the Stephan's Quintet shock, at the positions Ridge 1. No beam size convolution has been applied. The spectra have been shifted vertically for clarity. The arrows indicate the pre-shock H i velocities for the intruder galaxy and the intra-group medium.
