- Minutes (Yuzurihara)
- 120Hz glitches investigation during O3GK
- no update
- unify conda environment in Kamioka detchar computers, k1sum[01] and k1det[012] (YamaT)
- There are many computers/workstations in Kamioka site or Kamioka control room.
- Workstations (k1ctr*) use common conda environment by mounting the file server.
In DetChar computers k1{sum,det}[01], conda environment should be unified all DetChar resources, similar to workstations.
To prevent the trouble that DetChar experts might break the environment, the conda environments will be set as read-only permission.
Installation will be done by Kamioka members. After that, we need volunteers to test the DetChar tools on new conda environment.
- what is the time line?
- Installation will finished before the end of March. From April, the test will start. Volunteers are helpful.
- DQ flags for O4
In last PEM meeting, Yuzurihara presented the current status and received the helpful comments. [slide](https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=13970)
- We will change our plan to construct the data quality flag and will compute the BLRMS of gwpy to set the threshold.
- The review is necessary before O4. (probably very close to O4, because we need ER)
- DQR update
- no update
- Commissioning of GreenX
- In the last weekend, the commissioner tried continuous GreenX. During that trials, they found many short term lock loss (~10 ms). 10 ms is too short to follow the suspension motion, so it is likely that there are some causes of the lock loss except for the suspension motion.
The commissioner needs helps DetChar members to identify the cause or give a hint of the cause.

- progress of DQR
- igwn-alert is running more than 9days and receiving the MDC alert
next step is to connect the MDC alert with the launch TaskManager.
remained task is to develop InspiralRange issue
- lock loss study of GreenX
- From the Hveto result, the channel (K1:IMC-SERVO_MIXER_DAQ_OUT_DQ) was the most coincident channel with the lock loss of GreenX.
- unify the detchar computing environment (YamaT)
- scattered codes and applications (Omicron, summary page, ) over Kamioka computers are troubling.
- we plan to unify the environment by using igwn conda
- detail will be reported in next meeting
- (Darkhan) conda environment on k1ctr*. someone accidentally update someone's conda environment. administrator should prepare the conda environment?
- (YamaT) k1ctr* share the environment. this activity is not related to k1ctr* but k1sum[01], k1det[012]. we should separate the user environment and the environment for the DET tools
- (Darkhan) should avoid accidental mistake.

- (Yuzurihara) read BLRMS data and made the several plots with 1% and 99% percentile.
- When KAGRA will be locked as observation mode?
- hopefully after july, there will be lock trial for two monthes(?)
- When you set the 1% criteria, always you throw away the 1% data?
- We might need to consider the better procedure to care that point.
