Caption: Figure 4.

Top: volume-weighted mass spectrum for merging NSs (left, blue) and BHs (right, red) for a metallicity Z = 0.0002 (open dashed steps) and Z = 0.02 (filled steps). The vertical lines mark the value measured for GW190814 and corresponding uncertainties. Middle: same as in Figure 3, but here the mass ratio and primary mass distribution are weighted with two selection functions to mimic the dependencies affecting the detector accessible volume. Bottom: mergers’ chirp mass for metal-rich (filled red steps with dashed edge) and metal-poor (filled gray steps with solid edge) clusters.
