Notes. The columns report the CE efficiency αCE, mass-transfer accretion efficiency limit onto compact objects ηacc in units of Eddington-limit and the relative fraction of events in the parameter space slices: χeff > 0.1 and Mchirp > 15 M⊙, χeff > 0.1 and Mchirp < 15 M⊙, Mchirp > 15 M⊙, and q > 0.8.
