      • No updates
    • DQ flags for O4
      • slide

      • (Yuzurihara) read BLRMS data and made the several plots with 1% and 99% percentile.
      • When KAGRA will be locked as a?
        • 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


20220131 (Mon.)

  • Agenda
    • 120Hz glitches
    • Report from DQR hackathon

    • DQ flags for O4
  • Minutes
    • 120Hz glitches
      • No updates
      • Next step is coincidence search with signals around ETMY including local control sensors.
    • ITMX glitches
      • klog#19212

      • 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.
      • Both GEO and KAGRA's results are now computed and draft was also updated.
