Brute force coherence report for the lock reported in 20020 is available here:

At a first quick look:

• coherence with MICH and SRCL is still large at low frequency (fig 1 and 2)
• there is the usual coherence with AS power signals (fig 3)
• 64 Hz is coherent with PEM-EY_MAG_EBAY_SEIRACK_X_DQ, PEM-EY_MIC_VEA_PLUSY_DQ and PEM-EY_MAG_EBAY_SEIRACK_Y_DQ

More analysis in the future...
