... 1999)[*]
Throughout the paper we use observational data sets containing either 7 or 8 dates. This serves two purposes: first, H$\alpha$ in the last data set is not well fitted, meaning that systematic errors could, potentially, be large. Second, the effect of the longer time baseline, which helps to increase the accuracy of the explosion date, can be discerned.
