Fig. 5


Left: observed cumulative distribution of log(HαEW) for different SN subtypes. SN sites which show no Hα emission are plotted as having log(HαEW) = 0. The dashed purple line indicates SN IIn distribution using the nearest H II regions (see text for description). Right: matrix for K–S test result. The colour-coding is the same as in Fig. 3.
