Zeeman-splitting analysis of OH megamaser lines from IRAS 02524+2046. Upper panels: Stokes I and V spectral fits obtained using the method described in Sect. 4.2.1 (fitting method 1), while the lower panels display results from another approach in Sect. 4.2.2 (fitting method 2). For heliocentric velocity calculations, we adopted a rest frequency of ν₀ = 1667.3590 MHz, although some spectral features originate from the 1665.4018 MHz OH transition.
