Upper panel: the absolute error in each of the three Windkessel parameters after 4 s of estimation simulation, at different scalings of measurement (pressure and flow) covariances (scaled multiplicatively and uniformly for both). Baseline values are as given in “ROUKF-CLS verification against ROUKF using a Windkessel model” section Lower three images: the parameter convergence history with the measurement variances, \(w_P^{(i)}\) and \(w_Q^{(i)}\), scaled by 0.1, 4.8 and 10.0 (left to right). See “The impact of the choice of measurement error covariance” section for further discussion
