Dear Yves,

To stay in his same "scenario" I guess it is better to use his same yields for SNIa which are for these elements (or at least for the next future)

QIa(3)=  0.143           !      3)O16        
QIa(7)=  0.0425         !      7)Mg         
QIa(8)=  0.154           !      8)Si         
QIa(9)=  0.4        (*)   !      9)Fe

I hope the table is fine, let me know! Of course I am ready to change format or, for example put the mass fraction rather than the mass. ...then please send we the integral you obtain, just to have a cross check!

Ciao!

Gabriele

(*) this is a bit weird but it is what he uses in that paper... I prefer the value 0.6 that is closer to the observational values.
