KAGRA information


(1)IFO status

Stable, however, IFO unlock reason was reported due to alignment drifting as klog#14066.

Continuous locking time is becoming shorter and shorter to 1 hour level.

We might need to take alignment again.

The binary range is still 500 kpc ~ 600 kpc.

There seems to be unknown noise around 200 Hz widely.
