I analized the white noise shaker injection at positition 1 (EXC : K1:PEM-EXCITATION_EY0_RACK_1_EXC, K1:PEM-PORTABLE_EYC_RACK_EY0_ADC0_DSUB25_OUT_DQ).
There were no significant excess in the DARM.
I assumed the coupling from ACC -> QPDs are liner and applied the Coupling Function model.
I also analized the white noise shaker injection at positition 2 (EXC : K1:PEM-EXCITATION_EY0_RACK_2_EXC, K1:PEM-PORTABLE_EYC_RACK_EY0_ADC0_DSUB26_OUT_DQ).
Some very small excess in the DARM were found at 115, 250, 300, 660, 780, 855 Hz.
