Top: H₂ integrated intensities integrated over 4π steradian from each vibrational level compared to the input kinetic energy flux for model A and B. The total H₂ intensity is similar in the two models, 5.5 × 10⁻³ and 4.7 × 10⁻³ erg s⁻¹ cm⁻² sr⁻¹ for model A and B, respectively. Bottom: As the top panel, but for densities of 10²,10⁴, and 10⁶ cm⁻³, b = 1.0, and υ_s = 20 km s⁻¹. The maximum neutral gas temperature is given in brackets.
