Fig. 2.

Percentage error in velocity and wall shear stress (WSS) magnitude and error in their angle. The letters under the boxplots correspond to the letters under the example images in Figure 1, which also illustrates which parameters were varied: (1) Scatter amplitude (low-to-high signal-to-noise ratio). (2) Scatter density (low-to-high density). (3) Radial intensity (uniform to uneven). Note that the y-axis limits are altered between plots.
