Estimation of parameters. Density distribution of the median of the estimated posterior with respect to the true values of the parameters: Chirp mass ℳ (left) and redshift z (right) of the detected compact binary sources. Top panel: Mock 1. Middle panel: Mock 2. Bottom panel: Mock 3. The magenta line is a reference for equal values of true and estimated parameters. The blue contour encloses the 90% probability region.
