I have been able to run the noise budget by hand, after changing some of the Pcal channels used that have disappeared in the last two days from the raw data.

Figure 1. Shows that the noise budget thinks the OMC projection is high. Normally it is 2 orders of magnitude below the sensitivity curve.

Figure 2 shows that the OMC error signal spectrum is 3 orders of magnitude higher than usual. The sensing noise is three orders of magnitude higher.

Figure 3. In the lock of ~17:00 UTC the problem is no longer present. Maybe the issue was removed by the restart of the SDB1_OMC process that was done today by Alain around 15:00 UTC.
