Here is the quick analysis of the OMC lock and scan performed by the operator during the last maintenance:

Fig.1 shows the OMC lock. We reach about 13.7 uW of power on B1_PD3 when the OMC is locked on the carrier TEM00.
Fig.2 and Fig.3 show the OMC scan in temperature. The first order mode peak is about 14% of the TEM00 peak, which is not a very good alignment (this means that the offsets used for NI single bounce are not well tuned), but sufficient for this type of sanity check.
