- 120Hz glitches
- DQ flags for O4
- progress of DQR
- lock loss study of GreenX
- Minutes
- 120Hz glitches
- DQ flags for O4
- 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.

Report from LIGO Detchar F2F Meeting
- DQ flags for O4
- progress of DQR
- Minutes
- 120Hz glitches
- No updates
- DQ flags for O4
- (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.
- progress of DQR
- 120Hz glitches

- 120Hz glitches
- No updates
- Next step is coincidence search with signals around ETMY including local control sensors.
- ITMX glitches
- K1:VIS-ITMX_F3_LVDTINF_GAS_{IN1,OUT} have glitches.
- It seems to occur around AA chassis. (AA and cable replacement didn't help to improve situation).
- We will try to find glitches on other channels on the same ADC board.
This channel should be added to Omicron search on SummaryPages.
- DQR progress
- DQ flags for O4
- No updates
- O3GK paper
- Threshold used for computing a glitch rate was changed as SNR=6.5.
- It's a same criterion with LIGO, and Virgo.
