modes confirmation from transmissbility curves

[vibract]

Dear members,
I request you to please confirm the number of modes ( if possible with approximate modal frequencies) in the picture which can be found at

That curve is in between transmissibility ratio (acceleration ratios) and the excitation forcing frequency.

Regards

...without phase information, and an unknown resolution, tho it looks to be about 1 Hz.

What window was used?
