I analyzed the 70 -900 Hz injection data.
(The frequency resolution is set to the injection resolution)
I update my analysis:
I also analyzed the following data:
06:02:43 - 06:34:00 (JST)
50 -200 Hz with 1 Hz resolution
100 count injection
10 s in each frequency
The remarkable frequencies are 87Hz, 91Hz, 95Hz, 190Hz (see the PDF file).
