SNIa yields are computed from the
 full set of models for deflagration (W7, W70) and delayed detonation
 (WDDs, CDDs) scenarios by \citet{iwamoto99}. SNcc yields are
 integrated over a Salpeter ($x=1.35$) or a AY top-heavy ($x=0.95$)
 IMF, with abundance of the progenitor $Z=0.02$. Models for SNcc are
 taken from \citet[][No06]{nomoto06}, \citet[][CL04]{chieffi04} and
 \citet[][W95]{woosley95}.
