We present a new and homogeneous set of explosive yields for masses 13, 15, 20, 25, 30, and 35 M ☉ and metallicities Z = 0, 10 -6 , 10 -4 , 10 -3 , 6 × 10 -3 , and 2 × 10 -2 . A wide network extending up to Mo has been used in all computations. We show that at low metallicities ( Z ≤ 10 -4 ), the final yields do not depend significantly on the initial chemical composition of the models, so a scaled solar distribution may be safely assumed at all metallicities. Moreover, no elements above Zn are produced by any mass in the grid up to a metallicity ~10 -3 . These yields are available for any choice of the mass cut on request.
