Engineering Run 2 (2019/7/13)

• JST: Jul. 13, 2019, 12:00 12:37 - 18:00 JST

• GPS: 1247022018 1247024238 - 1247043618

Data related

• 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 considered lock segments by file units for convenience. If compared with lock segment(DetChar), this lock segment is small slightly.

Check point

• Check the available locked data(OK)
  • Summarize the data length
• Estimate power spectrum density(OK)
  • Sumarize information in pdf(OK?)
• Generate lock list and segment list(Skipped)
