Table 5: Summary of the metrics obtained with the different sampling
strategies and weighting methods. FW means flow-weighting, TW means
time-weighting. Grey figures are not significantly different from 0.\(F_{\text{yw}}^{**}\), \(F_{\text{yw}}^{*}\) and \(F_{\text{yw}}\)respectively refer to virtual sampling FW, dynamic and weekly sampling
FW and dynamic and weekly sampling TW estimates of young water
fractions. (1) denotes dimensionless variables.
