Comparisons on the light curves (shown in each top panel) for different distributions of ⁵⁶Ni (shown in the bottom panels), when the full integrals are used for both the direct and diffusive tail heating according to Equation (B6). In the middle panels, we plot the ratio of the local heating rate L ₅₆, which is usually what we wish to infer from the observations, to the total luminosity L.
