Notes. The columns report the model’s channel, either CE or SMT, CE efficiency αCE, the mass-transfer accretion efficiency limit onto compact objects ηacc in units of Eddington-limit, the local rate density at z = 0.01 (in Gpc−3 yr−1), the detection rate (in yr−1) and the median chirp mass Mchirp, effective inspiral spin parameter χeff and binary mass ratio q with their 90% CI for the intrinsic (underlying) and observed BBH populations. Bold text is used to indicate our reference model.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
