Temperature profiles of shocks from 5 to 20 km s⁻¹ (from top to bottom panels) propagating in media with density ranging from 10² to 10⁵ cm⁻³ (from left to right panels) and illuminated by a UV radiation field ranging from 10⁻¹ to 10⁴ (from colder to warmer pre-shock conditions on each panel), assuming a buffer visual extinction (top 12 panels) and 10⁻¹ (bottom 12 panels). All other parameters are set to their standard values (see Table 1). Models run with and without taking the UV pumping of the rovibrational levels of H₂ into account are shown in dashed and solid curves, respectively.
