True values of the primary component masses (top left) and lighter component masses (top right) distributions (analytic expression) in the source frame of the detected events for a simulation of O1−, O2−, O3−, and O4−like 3 observational years. The redshifts (bottom) distribution of the events is also shown. The network (S/N) threshold was set to (S/N)_thr = 12. In the same plots, the distribution (KDE estimation) of all the simulated (detected and not detected) events can be seen. The population, cosmological, merger rate, and detector parameters are given in Table 4.
