Comparison of the shape changes with T eff of the Hβ (left) and Hα (right) profiles at low (top) and high (bottom) metallicities. As in Fig. 4, the spectra were normalized by the 99th percentile of the flux in the shown wavelength intervals. Gaps in the spectra indicate telluric lines. Blue and green colored ranges denote the same FRs as in the inlays of Fig. 4, while the additional colored regions show the remaining seven relations ranked by the number at the top of each panel.
