Notes. All quantities were computed for 1000 M_⊙ of stars formed. ⁽¹⁾Total number of supernovae (CCSNe and PISNe) for 1000 M_⊙ ⁽²⁾Number of PISNe for 1000 M_⊙ of stars ⁽³⁾Total iron mass ejected from CCSNe and PISNe per 1000 M_⊙ of stars ⁽⁴⁾Iron mass ejected from PISNe per 1000 M_⊙ of stars ⁽⁵⁾Ratio of the total mass of ejected iron in each model compared to the Pop II, which contains no Pop III stars.
