Synthetic light curves in different bands for our ONe models with a central density of 1 × 10⁸ g cm^-3 and 2 × 10⁸ g cm^-3 and our CO model compared to the observed light curves of SN 2005cf and SN 1991T. The SN 2005cf light curve is dereddened for E(B − V) = 0.097 (Pastorello et al. 2007) and the SN 1991T light curve is dereddened using E(B − V) = 0.13 (Phillips et al. 1992). The distance modules are 30.76 for SN 1991T (Saha & Thim 2006) and 32.51 for SN 2006cf (Pastorello et al. 2007). For the bolometric light curve of SN 1991T we used a NIR correction based on normal SNe Ia.
