[Kenta, Yokozawa, Yuzurihara]
We performed the initial alignment. During taking the alignment for the PRMI, the earthquake happened and the BS was fluctuating ~3urad. We wait for a while and finished the initial alignment at 13:37.
We requested the PRFPMI_RF_LOCK to the LSC_LOCK guardian and confirmed that the interferometer can reach the PRFPMI_RF_LOCK at 13:50.
One concern is that the IR TRANS powers seem to be low <110.
We suceeded in restoring PRFPMI DC lock with 10W after the ITMX release by warming up.
Fig. 1, 2, 3, and 4 show the OLTFs of DARM, MICH, PRCL, and CARM, respectively. DARM, MICH and CARM seem to be lower to at most ~1dB than previous ones. PRCL seems to be almost consistent with the previous one.
Therefore, LSCs seems to be fine.
