Qualitative graphical representation of the three source-frame mass models considered in this Letter and described in Section 2.3 and Appendix C. The mass-distribution models displayed in the first two panels represent the mass ranges of black holes (BHs), while the third panel includes both BHs and NSs. The mass ranges shown are not to scale.
