Parameter estimation capability of different GW detectors (ET alone, LVKI, 3A#, ET+LVKI) in terms of relative error in the luminosity distance (Δd_L/d_L) corresponding to the GW detections of Figure 15. The top panels refer to ET-Δ, while the bottom panels to ET-2L. Each curve represents a different GW detector network, and the y-axis shows the cumulative number of GW detections with a relative uncertainty on d_L smaller than the values in the x-axis. The maximum Ω₉₀ used in the analysis is set at 100 deg² for each GW network, except for ET+LVKI for which it is set at 40 deg². The shown results are obtained using the fiducial population, the BLh EOS, both the uniform and Gaussian NS mass distributions, and 1ep strategy.
