SE SN light-curve templates. The templates were constructed by averaging the light-curve fits plotted in Fig. 2. The templates are represented by solid lines, their uncertainties by dashed lines. The r-band template light curve was used to estimate t(r)_max for seven objects having follow-up observations beginning past peak (see central panel). Depending on their subtype, that is, IIb, Ib, Ic, and Ic-BL, these objects are represented in green, blue, red, and magenta, respectively.
