      • 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.

    • 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.
