KAGRA full data
- m31:/data/full : Full KAGRA data
Low latency data
- m31:/data/ll_merged/ : Low latency data packed in 4096 seconds
- hydra:/data/ll_merged/ : Low latency data packed in 4096 seconds
- hydra: /data/ll-sharing/shm/llhoft/ : Low latency data (1 second) dumped from shared memory (retained only for 8192 seconds)
channel name
- From ER2 (DetChar)
- K1:CAL-CS_PROC_MICH_DISPLACEMENT_DQ (We used this channel.)
- K1:CAL-CS_PROC_IMC_FREQUENCY_DQ
Low latency data channels
- K1:DCS-CALIB_STRAIN_C10 16384
- K1:DCS-CALIB_STATE_VECTOR_C10 16
- K1:CAL-CS_PROC_IMC_FREQUENCY_DQ 16384
lock flag
- K1:GRD-LSC_LOCK_STATE_N = 157
data quality vector
- definition
- We cbc group should check the second bit is 1.
CBC lock segments
- We checked lock flag of each data and collected the locked data. We considered lock segments by file units for convenience. If compared with lock segment(DetChar), this lock segment is small slightly.

Summary of locked data CBC locked segment
Averaged PSD JGWdoc
- Power spectrum density (PSD) is averaged over 1 sec chunks by taking median.
Calculation time to search for signals(PSD estimate, template bank generation, matched filter, chi^2 calculation)
- Read 500 sec data : < 1 min
- Estimate PSD : 2~3 min.
- matched filter+chi^2 : < 1 min
Histogram of detection statistics JGWdoc
Time series of detection statistics JGWdoc
