    - Omicron triggers around 70 Hz
    - 70 Hz glitch was not real glitch. When we apply the hight pass filter with 10Hz or use DISPLACEMENT channel, the glitch disappeared.
    - (YamaT) In the end, should we use which channel? h(t) channel with high pass filter or DISPLACEMENT channel?
    - (Yuzu) h(t) channel will be straightforward.
    - (YamaT) If the analysis method is affected by the difference of waveforms, we will obtain the different results, such as SNR. Hveto result depends on magnitude of SNR (by threshold).

      * SummaryPages in igwn-py39 had worked well in gps mode (reported a few weeks ago).
      * TY want to gather the volunteer to test SummaryPages in daily mode.
    * gwpy can use 'NDSSERVER' environmental variable
      * We don't need to do the code hack for nds2.py in gwpy.
    * (Yuzu) In DAC call, I heard that operation test of `gw_data_find` is on-going on m31 by Compu&Soft members. It may be available in a few week.
   * DQR update (Yuzurihara)
    * I prepared the code of one task to compute inspiral range at the time of GW alert.

     * 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.
    * For details, see [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19963|klog#19963]] [[https://klog.icrr.u-tokyo.ac.jp/osl/index.php?r=19983|klog#19983]]
    * main channel K1:TMS-X_GR_PDA1_OUT_DQ

     * no update
    * DQ flags for O4
     * no update
    * 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 [[https://git.ligo.org/detchar/dqrtasks/-/issues/8|issue]]
    * lock loss study of GreenX
     * [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=19906|klog#19906]]
     * 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.
    * progress of DQR

      * 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.

      * Threshold used for computing a glitch rate was changed as SNR=6.5.
      * It's a same criterion with LIGO, and Virgo.
      * Both GEO and KAGRA's results are now computed and draft was also updated.
+    * analysis with 500~1000 images of spectrogram is on-going
    * unsupervised analysis didn't work well
    * LIGO's data set is always supervised one
   * Script to generate segment files (Uchikata, Narikawa)
    * error at m31 was fixed by using StateTimeSeries
    * Improvement of usability
     * added option to select the working machine
     * added option to select output directory
   * Investigation of silent run (Yamamura, Yuzurihara)
