[Alvin, Yuzurihara]
We checked the recent situation of the IPC glitches in the strain channel. The previous research is klog33237. Alvin-san made a script to count the number of glitches each day.
Figure 1 shows the histogram of IPC glitches during the silent run between April 1 and May 8. It seems that most of the IPC glitches occurred during the commissioning work.
The situation of IPC glitches during O4a for KAGRA is summarized in Uchikata-san's slide (JGWdoc). A similar histogram is shown on page 6. During O4a, the time of occurrence was concentrated around noon (see page 7), but this is not the case now. Occurrence times are uniformly distributed, as I checked.
