Hα line profile fits to Ca IIλλ8498, 8542, 8662 NIR triplet at 74.5 d and 121.3 d. In addition to linear background, each Ca II line is fitted assuming it has the shape of Hα profile at the same epoch. At 74.5 d the general shape of the profile is described by the fit, but at 121.3 d the asymmetric profile is well matched by the two redder Ca II lines. Velocity scale is measured from λ8662. The three Ca II lines are marked with dashed vertical lines.
