Number of SNe Ia within a Hubble time per 10⁵ M_⊙ of stars formed, corresponding to the different regions discussed in Sect. 3 and the different channels, calculated with our standard model (Sect. 2) and the models from our parameter study (Table 1).

The averaged SN Ia rate for the different channels separately and combined (the overall SN Ia rate) for different time intervals, assuming a starburst, calculated with our standard model (Sect. 2) and the models from our parameter study (Table 1).
