Table 1 Precision (p), recall (r), F-score (F), time-to-threshold (T2T), time-to-peak (T2P), and the normalized deviation between the threshold and the average value at the moment of flagging \([(\varepsilon _{\text {threshold}}^{\star } - \overline{\varepsilon _p^{\star }})/\sigma _{\varepsilon ^{\star }}]\), computed from multiple \(1000 t^\star\)-long signals at different Reynolds and wall distances.
