Median light curves in each filter separated by the median optical radiated energy, ﹩{\widetilde{E}}_{{\rm{rad}},{\rm{opt}}50}﹩ (g, c, G, r, o, and i from top to bottom). The peak and 50% measurements are marked by the horizontal dashed and vertical dotted lines, respectively. The shaded regions with different transparency represent P_15.9–P_84.1 and P_2.3–P_97.7 ranges. The two main groups of SNe IIn (faint–fast and luminous–slow) are clear, with their templates overlapping only at the P_2.3–P_97.7 level. The data used to create this figure is available in machine-readable format as the data behind the figure.
