Plane of final mass ratio q_fin <  1 and total final mass, m_tot. We report the estimation values with corresponding 90% credible intervals for the GWTC-3 signal (gray/black dots) and the posterior 90% iso-contour for a selection of those (gray dots and light gray curves). Resulting final mass ratios and total mass from our treatment are reported with color coding referring to different donor masses m_d, i in the simulation grid from Ge et al. series Ge et al. (2020), 2015, 2010). The assumption of completely non-conservative, purely isotropic re-emission, β = 1, channel is adopted in the top panel, while the bottom panel shows the results when switching on an efficiency for L₂ mass outflow of υ = 0.75. Solid gray, dashed lines delineate regions where the primary and secondary can have a mass below 3 M_⊙, and where both objects in the binary have masses above 3 M_⊙.
