Same as Fig. 6, but a composite model fit (red solid lines) that includes an additional B star component (green dashed lines) as secondary. The main parameters of the secondary model are T_* = 31 kK, log L/L_⊙ = 4.22, and log g_* = 4.2. We applied faster rotation (v sin i ∼ 140 km s⁻¹) and blue ward shift (v_rad ∼ 100 km s⁻¹) in the secondary model relative to the primary. The primary model (dotted brown lines) is the same as the one used in the single star fit (see Tables 3 and 4).
