I had a look at LSC_DARM coherences with ENV* channels.
here the bruco table: 1800s from May 7, 6:05 UTC, https://scientists.virgo-gw.eu/DataAnalysis/bruco/2017-05-07/LSC_DARM_1178172318_ENV/
Figure 1 is the "ENV budget" made projecting coherences, channels are divided by Type of noise (RED are all *ACC* and *SEIS* channels, and so on ... see the plot legend)
- major coherent contribution is seismic, 150-450Hz
Figure 2 shows the SEISMIC "sub-budget", indicating LOCATIONS of most coherent seismic channels:
- small line at 31Hz (... it is NOT the big structure at 29.8 Hz) and 101Hz line are coherent at IB tower (Figure 3)
- structures in the 150-450Hz zone look mostly coherent with accelerometers in DT zone (Figure 4)
I extracted the name of max coherent channel at the most prominent spectral peaks:
% freq(Hz) (ASD) maxCOHE channel
f=31.01 (ASD= 2e-07): 0.13 V1:ENV_IB_ACC_X
f=101.07 (ASD= 2.4e-08): 0.52 V1:ENV_IB_BD_ACC_Z
f=206.42 (ASD= 2e-09): 0.30 V1:ENV_EDB_ACC_Z
f=269.41 (ASD= 8.6e-09): 0.29 V1:ENV_NI_CT_ACC_Z
f=336.79 (ASD= 2.7e-09): 0.58 V1:ENV_DT_ACC_Z
f=409.55 (ASD= 3.8e-09): 0.04 V1:ENV_DT_ACC_Z
f=440.19 (ASD= 3.6e-09): 0.09 V1:ENV_DT_ACC_Z
f=456.54 (ASD= 5.7e-09): 0.19 V1:ENV_SPRB_LINK_ACC_Z
f=463.01 (ASD= 4.9e-09): 0.30 V1:ENV_NI_ACC_X
