Comparisons of the ZAMS mass-remnant mass relation between the updated BSE from within NBODY7 and StarTrack, for different Z and remnant-formation prescriptions. For Z = 0.002 and Z = 0.02, PPSN/PSN do not affect the ZAMS mass-remnant mass relation since the He-core mass never reaches the PPSN/PSN threshold (see B16). The mass gap between the NSs and BHs for the F12-rapid cases is indicated with the grey horizontal lines, as in the previous figures.
