Here are the results of the complex fitting. The residuals are bigger this time, but still probably small enough to be ok(?), with the possible exception of ITMY PITCH (due again I think to the data points straddling the resonance).
ITMY YAW actuator response complex fit
-- Fit completed after 282 iterations--
Started with: Gain = 3e-05,
Q factor = 5,
Pole frequency = 0.6776,
Fit results: Gain = 1.14673e-06,
Q factor = 12.9471,
Pole frequency = 0.766531
Residual (normalised against the sum of input datapoints) = 0.0688174
