LHO LVEA Tilt Studies at Roam8--With wind from ~+X

Last entry from Roam position 7, see 37334.

At Roam8, a meter or so further +X from Roam7, the spectra would suggest this location is not as quiet (wind response tilting) as Roam7.  However, this wind is from the NNW rather than our usual S or SW for previous views.  Also, while the Y dof seems more tilty for STS2-C (HAM5), at the lowest frequencies, HAM5 seems less tilty below 100mHz for the X dof.  I'm not sure if this conclusion is valid when the sensor is noisier during the quiet period???

Attached are the usual wind plot and sensor spectra.  The quiet wind time is 11 July 1200utc and the windy time begins 0230utc on 11 July.

Correcting the above spectra plots.  I forget to edit the titles of the plots indicating the location and wind details.  These have been corrected and attached here.
