Since there are several TFs, which has high coherence with DARM, I measured them precisely.
Measured data are stored at /users/Commissioning/data/NoiseBudget/TFs/2023/0629/.

Following DoFs have high contributions to the DARM.
1. MICH2DARM
2. PRCL2DARM
3. ETMX_MNL2DARM
4. ITMX_MNL2DARM
5. BS_TMY2DARM
6. SR3_TMP2DARM

Figure 1 shows the comparison with SUM of above noise contributions and the sensitivity.
I used the spectra from 18:00 to 18:10 on 14th of June.

Below 60 Hz, the sensitivity can be almost explained with the above noises.
