Fig 7. Comparison between the simulated and measured Euler angles for 11 flight sequences.

The symbols denote the species (○: C. perspicillata; +: C. brachyotis); the colors identify each flight sequence. For clarity, every fifth data point during each flight sequence is plotted. For all flights, after subtracting the angle at t = 0 so as to remove bias, the correlations between the measured and predicted roll, pitch, and yaw angles is R ² = 0.687, 0.935, and 0.721, respectively.
