As Fig. 2 for systems that form SNe Ia through the SD_He channel. Symbols A_He, B_He, and C_He indicate groups that are distinguished based on the evolutionary stage when the primary fills its Roche lobe, the number of CE phases necessary to evolve to a SN Ia, and the type of donor star transferring mass to the CO WD: A_He = HG, no CE, with He-MS donors; B_He = HG, 1 CE, with He-HG donors; C_He = TP-AGB, 1 CE.
