Fig. 11. Mean pitch. (A) Correlation between downstroke deviation and mean pitch
from each wingbeat cycle. Regression lines for five individuals super-imposed.
A relatively strong correlation exists within each individual
(R2=0.65 turquoise, 0.87 green, 0.97 orange, 0.83 pink,
0.76 purple), but the correlation differs across individuals (total
R2=0.49). (B) Upstroke lift from
Fig. 10I, with regression
lines for the same five individuals from A super-imposed.
