Average cumulative mass of different elements (and total metallicity Z) injected by a mono-age population with mass 500 M_⊙. Colors indicate different sources as labeled in the legend of the upper left panel. Except for SNIa, filled lines show the yields from NUGRID, while dashed lines show those from Limongi & Chieffi (2018) with different models (0, 150, 300 km s⁻¹) shown with thicker lines for increasing rotation velocity. For SNIa, the filled (dashed) line shows the result with a delay time of 38 Myr (100 Myr).
