Print this reportOmicron triggers around 70 Hz(Uchikata, Yuzurihara, YamaT)
Currently, we can see glitches around 70 Hz at all times in the summary page. For example, https://gwdet.icrr.u-tokyo.ac.jp/~controls/summary/day/20230528/lock/glitches/
However, these glitches disappear when we apply the highpass filter or use the DARM_DISPLACEMENT channel. Therefore, they seem to be produced artificially by Omicron.
Possible reason may be the failure of capturing the large dynamic range in the low frequency range.

Interesting. Gritch tools are important for quick commissioning, so we are happy if someone would check whether there would be bug or so...
