Profiles of temperature (top), atomic, molecular, and ionised hydrogen densities (middle), and radiation field (bottom) for the fiducial shock (Table 3). For the radiation field, we show the total emission computed with Eq. (7) (violet) and the contributions to this total by Lyα (red), Lyβ (cyan), and two-photon continuum (blue). The left column shows quantities in the radiative precursor, with distance increasing towards the left (i.e. distance from the shock front), the middle column shows postshock quantities with distance increasing towards the right in log scale while the right column is the same as the middle but in linear scale. Thick lines show results including the UV treatment, while thin dashed lines have no UV included.
