Notes. Columns indicate the number of nodes in velocity (Nv), magnetic field strength (NB), and inclination (Nγ) for the component using the cool umbral model from Collados et al. (1994) as initial guess. Rows correspond to models with one component (first row), two components including a non-magnetic atmosphere (second to fourth rows), and two magnetic components (fifth to last rows). Each row indicates the number of nodes in velocity (Nv2), magnetic field strength (NB2), and inclination Nγ2 of the second component. The BIC value of the best model (Nv = 5, NB = 2, Nγ = 2, Nv2 = 5, NB2 = 2, Nγ2 = 2) is highlighted in bold.
