Mass cut for single (top) and binary (bottom) stars for the F23 progenitor models. The mass cut is equal to the baryonic mass of the cold neutron star. The red squares represent the original F23 explosion models, and the blue circles represent the explosions carried out in this work. Left: quantities shown as a function of initial ZAMS mass. Right: quantities shown as a function of pre-supernova compactness. The mass cut is larger in the models simulated in this work, and as expected, there is a clear correlation with compactness. However, the scatter in the mass cut for high-compactness progenitors is much larger for the F23 single-star models (see the discussion in the text for more details).
