Spectra over a variety of epochs for selected models which range from the bright to faint end of the model sequence alongside three observed SNe Iax: SN 2012Z (Stritzinger et al. 2015), one of the brighter members of the SN Iax class, SN 2019muj (Barna et al. 2021) which is an intermediate brightness SNe Iax, and SN 2019gsc (Srivastav et al. 2020) which is one of the faintest SNe Iax (see Figs. 13 and 17). The observed spectra shown here were obtained from WISeREP¹ (Yaron & Gal-Yam 2012). All times are relative to explosion and in all cases real flux is plotted on a logarithmic scale. There is no data for SN 2019gsc 6 days after explosion and in the lowest panel the spectra were taken 23 days after explosion for SN 2012Z and SN 2019gsc. All observed spectra are flux calibrated to match the photometry and corrected for distance, red shift and reddening.
