Here's a BruCo scan for last night lock:

Focusing on the band between 20 and 50 Hz, there isn't any large coherence. However:

• angular controls show a bit of coherence (MICH_Y and CHADR_Y).
• there is coherence with the input beam control (INP1_Y) which also shows up with the ISS second loop QPD
• SRCL is still the largest longitudinal control, but coherence isn't very high.
