Gabriele's coherence table, for most of them the largest coherence is with other channels which I list on the side:
1) 10Hz harmonics (30,40,60,70,80,90Hz) mainly coherent with channels Ti_1PPS_Atomic, Ti_1PPS_GPS_Old Ti_1PPS_GPSMaster, TolmPhoton_processed_packets
2) line at 28.61 Hz: is coherent with NI tower seismometer Em_SETONT01 (0.46) and Sc_NI_tyCorr (0.33) ...
3) line at 29.05 Hz: with MC seismometer Em_SEBDMC03 (0.64) ...
4) line 36.54 Hz and its harmonic at 73.05 Hz: coherent with channels Pr_6MHz_WE_PhErr (0.83) Pr_6MHz_NE_PhErr (0.83) Bs_PMC_DR_DC_1 (0.68) Bs_PMC_DR_DCHF (0.67)
5) 43.70 Hz and its harmonic at 87.46 Hz : coherent essentially only with magnetometers Em_MABDWE01 (0.67), also see 29268
6) a triplet at 57.19 Hz, 57.43Hz and 57.83 Hz: are also coherent with Sc_NI_RM_CoilU (0.49) Ca_NI_RM_CoilR (0.38) ...
Figure shows the size in hrec of lines 44 and 88 Hz, and the 57Hz-triplet.
