    • 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

    • klog#19671

20220131 (Mon.)

• Agenda
  • 120Hz glitches
  • Report from DQR hackathon
  • DQ flags for O4
  • Master thesis (Morisue-san)

20220117 (Mon.)

• Agenda
  • 120Hz glitches
  • ITMX glitches
  • DQR progress
  • 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

    • JGW-G2213721

  • 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.
