Combination of the photosphere and spot models for the MgH A2Π–X system at 5200 Å for a model star with vsini = 10 km s-1, Tphot = 5000 K, Tspot = 4000 K, and with (i) left panel: 5%, 10%, and 20% (solid, dashed, and dotted lines, respectively) magnetic field of 3 kG, (ii) right panel: 10% magnetic field of 1 kG, 2 kG, and 3 kG (solid, dashed, and dotted lines, respectively) magnetic field. Stokes V was calculated with an inclination angle of the magnetic field γ = 0° and Stokes Q with γ = 90°.
