Similar to Figure 7, but for the 445 d spectrum (blue lines), compared to radiative transfer calculations of SN II spectra at 450 days for progenitors of various initial masses (colored lines as labeled). Models for 9 M⊙ are from Jerkstrand et al. (2018), while models for the other masses are from Jerkstrand et al. (2014). The model spectra were normalized to match the observed flux integrated between 6900 and 8200 Å.
