Parameter distribution for the mock LISA data analysis. The top-left panel shows the signal-to-noise ratio (S/N) distributions. Gravitational wave events are assumed to be detected if S/N > 10, indicated by the vertical dashed line. The 90%-confidence error in the sky localisation is shown in the bottom-left panel. The dashed line delimits the shaded region, which corresponds to the events with sky localisation poorer than 10 deg². The relative 90%-confidence error distributions for z, M_chirp and q, and for χ₁ and χ₂, are shown in the right panels, top and bottom respectively. Most parameters are recovered with small uncertainties. The majority of mergers have sky localisation worse than 10 deg² at the time of the merger.
