Upper panel: LTE fit of strongly Zeeman split Fe iii lines at 5063 and 5074 Å with  ⟨ |B| ⟩  = 4800 G and vsini = 3 km s^-1. The fits are shown to the two spectra (#3 and #4) that clearly reveal splitting of the 5074 Å line. Lower panel: comparison of LTE fits to Si iii 4552, 4567 and 4574 lines in spectrum #3 with ξ_t = 5, vsini = 6 km s^-1 and no magnetic field (upper curves), to LTE fits (lower curves) with the magnetic model of the upper panel.
