Effect on the misclassification ratios of applying a rejection criterion on the type probability. The left/right panel shows the weighted misclassification ratios (f_loss,w and f_gain,w) for the thermonuclear/core-collapse SNe along with the fraction of rejected candidates (N_rej/N_app) for a given limiting type probability (P_lim). This information can be used to select an optimal P_lim to avoid misclassifications without rejecting too many candidates. For details see the text and Table 3 (this figure is available in colour in the electronic version of the article).
