Posterior distributions of the parameters θ_GW as inferred for our fiducial binary at d_L = 100 Mpc (left panel) and d_L = 50 Mpc (right panel). Blue contours give the posterior distribution when only using the GW data, whereas the green contours give the posterior distribution when using both the GW and radio data. The dark and light shaded regions give the 68% and 95% confidence levels, respectively, for all posteriors shown. The fiducial injected values are indicated by the dashed black lines.
