Multi-component line fitting of He I 1.083 μm (a) and Pa β 1.282 μm (b) at 9 d with with Gaussian and Lorentzian components. The He I 1.083 μm line profile (a) was fitted with two broad Gaussian profiles with FWHMs of 5250 and 6010 km s⁻¹ for absorption and emission, along with two intermediate-width (IW) Gaussian profiles with FWHMs of 1000 and 670 km s⁻¹ for absorption and emission. The Pa γ 1.094 μm that overlaps the He I 1.083 μm was simultaneously fitted with an intermediate-width Gaussian profile with FWHM of 980 km s⁻¹. The Pa β 1.282 μm line profile (b) was fitted with two broad Gaussian profiles with FWHMs of 4790 and 5150 km s⁻¹ for absorption and emission, respectively, and an intermediate-width Lorentzian emission profile with FWHM of 720 km s⁻¹ (red).
