Because the DARM sensitivity and vibration level around OMC area became better compared from previous measurement,
we performed the vibration injection test to OMC leg again.
The situation is same with previous measurement.
We will analyze the data.
The noise projections for the significant frequencies are listed here. (See JGW-G2314867 for all plots)
In any case, the estimated noise budgets are below the current sensitivity.
Sometimes the ACC signal became larger than the reference around 700Hz even if the injected frequency is other. However, we can ignore it because there was no significant excess in the DARM when we injected around 700Hz directly.
Noise projection results are not changed so much depending on the injection power.
This is the noise projection for all frequencies.
(Not yet taking summation)
A comparison of the response function with the previous measurement (in Feb.) is not performed yet.
