This is to report that the violin resonances were much larger on July 24 and 25, which produced cross-coupling effects and impacted a large band for CW and stochastic analysis. The situation seems to be much better on July 26 although only 5-hr data were collected on July 26. Also there were a lot new lines from ~ 20Hz to 70Hz, which got better on July 26 too.

There seem to be quite a few entries about the rung-up violin modes and this probably is an known issue, but we are flagging this from the perspective of CW/stochastic analysis. 

Attached are the full 4k and 0-100Hz spectra on July 24, 25, 26, respectively.
