In the low frequency, there's coherence with MICH/SRCL (fig. 1), angular signals (fig. 2) and ITMY L2 control (fig. 3, not sure what is the control topology, maybe this is ok)
One very interesting thing: there is a significant broadband coherence with IMC_DOF_4_P (fig. 4) and with IMC-PWR_IN (fig. 5)
Lines at 57 Hz and 114 Hz are coherent with magnetometers.
