Effects of level dissolution in the UV (left) and the optical and NIR (right), for models s8a and d6v (see Table 2). Displayed is the deviation of the emergent fluxes, , without and with accounting for level dissolution, as calculated by  CMFGEN. The results for model s8a have been vertically shifted by 0.04. To guide the eye, the gray-shaded region refers to deviations of ± 1% for the UV range, and of ±0.5% for the optical and NIR range, respectively. For clarity, wavelength ranges with λ < 930 Å and λ < 3700 Å (regions close to the Lyman and Balmer edges, where, as expected, larger changes are found) are not displayed. All wavelengths refer to vacuum.
