IVyTools discharge and uncertainty results for eight benchmark image velocimetry videos: Uncertainty Analysis
This child item contains the uncertainty analysis data for all eight Video Globe Challenge 2020 (VGC2020) sites processed with IVyTools. The file extracted_ivy_data_v1.4.0.0.csv contains extracted uncertainty component values for both ISO 748:2007 and Interpolated Variance Estimator (IVE) methods, including total uncertainty, individual component uncertainties (width, depth, point velocity method, velocity, number of stations, systematic, velocity coefficient alpha, and rectification), and the fractional contribution of each component to total variance.
Uncertainty values are expressed as fractional proportions (not percentages). To convert to 2-sigma (95 percent) confidence intervals in percent, multiply u95_q values by 100.
