Fits of some spectral details in our theoretical spectra shown in the right panel of Fig. 4 to the observed features in G 224-58 B spectrum: MgH A²Π − X²Σ⁺ band system at 5200 Å (top left), lines of Na I resonance doublet (top right), lines of resonance doublet of K I (bottom left), subordinate lines of Na I (bottom right). Model atmosphere and normalisation point are the same as for Fig. 4.
