  "description": "This child item contains summary comparison tables presenting IVyTools discharge results alongside Video Globe Challenge 2020 (VGC2020) reference values. Two CSV files are included:\n<ul>\n<li><strong>IVyTools_VGC2020_discharge_summary.csv:</strong> Corresponds to Table 2 in Engel and others (2026). Contains the IVyTools discharge result, reference discharge, uncertainty estimates (International Organization for Standardization [ISO] 748:2007 and Interpolated Variance Estimator [IVE] methods), velocity coefficients, and percent deviation from reference for each of the eight VGC2020 sites.</li>\n<li><strong>IVyTools_VGC2020_alpha_sensitivity.csv:</strong> Corresponds to Table 3 in Engel and others (2026). Contains the adjusted discharge (Q_adj) recomputed using the VGC2020 reference alpha values, and the resulting percent deviation from reference discharge.</li>\n</ul>\nAll uncertainties are reported as 2-sigma (95 percent) confidence intervals.",
