BVRIYJH bolometric light curves for our sample of 37 SE-SNe. SN types are listed in the legend. The dashed grey curves show reference 56Ni decays, with a factor of two in 56Ni mass separation. From these reference slopes its can be seen that all SE-SNe within our sample decline steeper than the 56Ni decay after ∼60 days past explosion.
