Delay time distributions for a subset of SN Ia progenitors shown in Table 1. Top panel: mergers that involve one or more ONe WD (blue), and double detonations where the accretor is an ONe WD (orange). Bottom panel: mergers that involve two CO WDs where the primary (more massive) WD is ≥0.9 M_⊙ (blue), and double detonations where the accretor is a CO WD with mass ≥0.9 M_⊙ (orange). For both panels the combined DTD is shown in grey.
