The IFO has been recovered.
- LSC guardian could reach to OBSERVATION
- Due to the power drop of the GRY, the FNC cannot been locked. Therefore, I and YamaT-sensei enter the mine and align the green fiber as suggested by Sugimoto-kun
- I changed the FNC gain to -20 dB and GRY-PDH gain to 6. The UGF of PDH loop is around 4 kHz.
- YamaT-sensei fixed the IX Tcam.
- The alignment is terrible. I guess we need to tweak the IMMTs.
