We performed the shaker injection for the MCF chamber, +X side, on the bean duct. (See the photograph)
10:05 - 10:20 JST, 80- 980 Hz swept sine.

This is a very preliminary result of the noise projection for the vibration on the MCF chamber, +X side.
If it is believable, environmental noise reduction below 200Hz might be worth it.

In the previous log, I plotted the noise projection for the points where the DARM excess was larger than 2 times of the background.
To be better seen here plotted the points where the DARM excess was larger than 3 times the background.
(The mistake of the y-label for the ACC power (unit) is also fixed.)
