The tool in snlite.tbz generates simple radioactive decay models of late-time supernova light curves. This tool was used in this article and this article on SN 1987A.

The tool in lc1a.tbz generates simple supernova type 1a light curves. It is based on the expressions in Arnett 1982 and Dado & Dar 2015 where the bolometric luminosity is given by \begin{equation} L_b(t) = \frac{1}{t_r^2} \exp \left ( \frac{-t^2}{2 \ t_r^2} \right ) \int_0^t t \ \exp \left ( \frac{-t^2}{2 \ t_r^2} \right ) \ {\dot E}(t) \ {\rm d}t \ , \label{eq1} \tag{1} \end{equation} where $t_r$ is the rise time and ${\dot E}(t)$ is the energy deposition from radioactive decay of $^{56}{\rm Ni}$ and $^{56}{\rm Co}$ and positron heating. The tool's default set of parameters is aimed at SN 1992bc:
