From the safety injections on 2023-10-24 it seems like three channels (not in the usual H1 channel list) have gained a coupling to h(t) in the frequencies around 100 Hz since the 2023-07-26 injections. The low-frequency coupling is not new. Here are the channels: H1:ASC-OMC_RIN_OUT_DQ, H1:ASC-OMC_B_NSUM_OUT_DQ, and H1:ASC-OMC_A_NSUM_OUT_DQ.

Not sure if this is expected or worrying, but I thought I'd report it.
