Notes. The final mass of the primary and secondary, Mf1 and Mf2, and the amount of hydrogen in the envelope MH are given at the time of explosion, together with the luminosity log(L/L) and effective temperature Teff of the primary and secondary at the onset of central carbon burning. If the evolution of the binary system ended because of formation of a contact binary, the parameters cannot be determined and are indicated by “/”.
