Model predictions for the chirp mass Mchirp, effective inspiral spin parameter χeff, cosmological redshift of merger zmerger, BBH merger timescale Tmerger, metallicity Z and the binary mass ratio q distributions of binary black holes observables at design sensitivity. Lighter colors represent larger contour levels of 68, 95 and 99%. We arbitrarily divide the two dimensional histogram Mchirp vs. χeff with red lines into three regions at χeff = 0.1 and Mchirp = 15 M. Region-A contains 80% of the events, 10% are in Region-B and 10% are in Region-C. For illustrative purposes, all histograms are plotted with a smoothing scale of 0.8 bins with the exception of zformation vs. χeff, zformation vs. zmerger, q vs. χeff that have no smoothing.
