Inversion results for EB profiles. The observed profile is shown as a black solid line. The colours of the fits correspond to the colours of the spectra, shown in Figs. 6–8. The total fit is given as a coloured solid line. The emission component (dashed line) and the absorption component (dash-dot line) are overplotted. The red and purple fit for EB1 have been obtained using only one component (solid line). The values for the parameters are shown in Table 4.
