Notes. The secondary is, for every model, at the start of mass transfer on the giant branch. The column with *1/*2 indicates which star in the binary system explodes first. The time difference between the two stars reaching carbon burning is indicated if star 2 explodes before star 1. The other symbols have a similar meaning as in Table A.1.
