They are the DC responses.
I put the resonant frequencies that Leo reported in the wiki to obtain the DC response.
The resonant frequencies I used are :
f_BS = 0.957 Hz
f_ITMX = 0.966 Hz
f_ITMY = 0.988 Hz
Also I assumed that all the Q-values are 5 due to the damping.
I've got confused
1) Are these the DC responses of the coils? If that is true, we need to specify the resonant frequency of each suspension to get the AC response.
2) Are these the AC responses well above the resonant freqs? In that case, The responses should be x.xxx / f^2 [m/counts]
BS = 3.69e-08 [m/counts]
ITMX = 8.89e-09 [m/counts]
ITMY = 9.22e-09 [m/counts]
