SQZ is ready for IFO
After HAM7/FC GVs were open this morning, I aligned FC1/2 and FC GR is locked. FC GR trans is ~110, which is reasonable.
I measured NLG following 76542. The measured NLG is 16 (0.247/0.0154=16), which is a bit lower than the last measurement in 78000. The OPO temperature is very different from before as shown in the attached SDF.

I measured NLG again. The measured NLG is 17 (0.0041/0.00024=17). This is consistent with previous measurement and OPO temperature is closer to the previous value as shown in the attachment.
