Notes. The total yield is the elemental mass yield for the total ejected material. Mass yields are in  M and the gas mean molecular weight μgas is in g cm-3. Parameters for the SN ejecta with a progenitor mass of 15 M: explosion energy Ekin = 1 × 1051 erg; He-core mass =4.14 M; ejecta velocity =2000 km s-1; and γ-ray Optical depth τγ = 17.5. Parameters for the SN ejecta with a progenitor mass of 19 M: explosion energy Ekin = 1 × 1051 erg; He-core mass =5.62 M; ejecta velocity =2000 km s-1; and γ-ray Optical depth τγ = 23. Nitrogen, N, is only present in Zone 6 with a yield of 4.3 × 10-3 for the 15  M progenitor and 4.5 × 10-3 for the 19  M progenitor.
