Fig. 6


Left and centre: observed cumulative distribution of parent stellar population age and progenitor initial mass for different SN subtypes. SN sites which show no Hα emission are plotted as having an age of 40 Myr, corresponding to the single-star SN progenitor lower mass limit of 8 M. Right: matrix for K–S test result. The colour-coding is the same as in Fig. 3.
