Main properties of 100 O5-like BBH events with S/N > 25 drawn from MICECATv2 with three host weighting schemes: unweighted (mock0, gray), weighted by stellar mass (mock1, blue), and weighted by stellar mass squared (mock2, red). Top panels: Distribution in the sky localization (90% C.L.) versus luminosity-distance uncertainty plane color-coded by the network S/N. Bottom panels: Distributions of source redshift, number of galaxies within the localization volume (N_gal, vol), host galaxy stellar mass, and i-band magnitude for the various samples; the arrows indicate the median values. The dot-dashed lines show the background redshift distribution of potential BBH host galaxies used to generate GW events. The vertical dashed line shows the mass and magnitude cuts that are applied in this work to study incompleteness effects.
