- 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?
