Mass cut for the LC18 progenitor models. The red squares represent the original explosion models of LC18, and the blue circles represent the explosions carried out in this work. Left: mass cut as a function of initial ZAMS mass. Right: mass cut as a function of pre-supernova compactness. Note that all metallicities and initial rotational velocities are shown on the same plot. The mass cuts are generally larger for the LC18 explosions, especially at high compactness, although both in this work and in the original LC18 one can see a clear correlation between compactness and mass cut (see the discussion in the text for more details).
