The coherence in pitch direction is not very good in the last elog. Therefore, some new measurements were performed.

1. The first four figures are measured with gaussian noise excitation, resolution is 0.01Hz.

2. Figure 5 shows a measurement of END_yaw TF with uniform noise excitation. The measurement result is a bit different with guassian excitation.

3. I increase the input pitch gain from 0.3 to 2. The new TF is shown in figure 6.
