Note: the data in Fig. 5A, B and C were used for case 1, 2 and 3, respectively. SΔΦ and SΔΨ are the signs of ΔΦ and ΔΨ (see Fig. 3 for definitions),respectively, which represent the bilateral difference in wing position qualitatively. dRoll and dYaw are the variation of roll and yaw, respectively,from the previous sampling to the current. SdRoll and SdYaw are the signs of dRoll and dYaw, respectively, which represent qualitatively the changing tendency of the corresponding Euler angles. In the cross-correlation analysis, Lag indicates the lag of the changing tendency of the Euler angle response to the bilateral difference in wing position; Coeff., the corresponding correlation coefficient. The maximum range of positive and negative lags for a series was set as 5, and only the maximum coefficient (absolute value) and the corresponding lag are listed here. The negative value of lag indicates advance and the negative value of coefficient indicates decreasing Euler angle accompanying the positive bilateral difference in wing position, and vice versa
