Print this reportMy previous summary for the KAGRA lock status on Dec. 18 was
but, to be more precise, the locked state can be further classified into two:
Total lock duration: 7761 sec (2.156 hrs) for K1:GRD-LSC_LOCK_STATE_N>=300 (the Locked (LSC) state)
Total lock duration: 6572 sec (1.826 hrs) for K1:GRD-LSC_LOCK_STATE_N=1000 (the Observing state)
The Duty cycle value I showed previously was obtained from the former figure. If we use the latter figure, it is 7.61%.
