I checked the spectrum as shown in Fig.1. (red) timing around large glitch (blue) silent (3:00:00 JST)
As shown in Fig.1., the 190 Hz line became larger (Other line also?) and tail can also seen.
From the previous violin mode identification in klog32643,
189.92188 EYIMP 11/13:08:00
So, ETMY affect to this glitch
Is this a hint to improve the sensitivity below 100 Hz?
Anyway, we will check the glitch of ETMY.
