Absolute fluxes of selected CO, H₂O, and OH lines predicted by Kaufman & Neufeld and Flower & Pineau des Forêts models and shown as a function of shock velocity and for pre-shock densities of 10⁴ cm^-3 (left), 10⁵ cm^-3 (center), and 10⁶ cm^-3 (right). The latter models are available only for the pre-shock densities of 10⁴ cm^-3 and 10⁵ cm^-3. OH 84 refers to the OH J = ⁷/ 2−⁵/ 2 doublet at 84 μm.
