RMSE between the time lags acquired from the simulations and their linear fits for a reference frequency of ν₁ = 32 GHz. The points are color-coded according to the time lag window length; 100 (magenta), 200 (red), 300 (green), and 400 (blue) r_g/c. The color-dashed lines denote the mean slope of the best-fitting (RMSE < 5) time lags for the vertical lines, while the horizontal lines denote the mean RMSE of the entire population. The grey dashed line, with standard deviation area, corresponds to the linear fit to the VLA-only data from BR15, which is A = 42 ± 14 cm/min. The contours denote the 25%, 50%, and 75% levels of the normalized kernel density estimations for each of the window length results (in the corresponding colors). Figure 7 displays the results for a reference frequency of ν₁ = 19 GHz, which was the base assumption throughout this work.
