Production factors [X/O] of element X and oxygen with respect to their solar ratio. We use the solar abundances from Asplund et al. (2009). A value of zero indicates the same ratio as in the solar system. The yields of each star are weighted by a Salpeter IMF and then normalized to one. The blue line shows the yields obtained in this work; the red line shows the yields from WH07 assuming that everything explodes; the cyan line shows the yields from WH07 adopting the explodability derived in this work; and the green line shows the yields from C19.
