Left panel: UVOIR light curves for our CMFGEN simulations, together with the inferred light curve for SN 1987A (the shaded area is bounded by the UVOIR light curves inferred by Catchpole et al. 1987 and Hamuy et al. 1988). Right panel: same as left, but now for the simulations a2, a3, a4, and a5 (which differ primarily in ejecta kinetic energy and ⁵⁶Ni mass). We also show the total decay power emitted (dashed line) and absorbed (dash-dotted line) for each model.
