Template light curves for the five core-collapse supernova types at z = 0.5. The upper panel shows the R light curve for the IIP subtype as thick solid (black), the IIn subtype as dash-dotted (red), the IIL subtype as solid (green), the Ibc-normal subtype as dotted (black) and the Ibc-bright subtype as dashed (blue). In the lower panel the R − I colour evolution for the five subtypes are shown using the same line styles (this figure is available in colour in the electronic version of the article).
