LHO LVEA Tilt Studies at Roam6--With wind from SW

Refer back to LHO aLog 36739 to walk back through these reports.  I'll attach the updated map to a comment shortly.

NOTICE--There is a location that may be quieter than ITMY STS2!!

Roam6 is located just west of of BSC4s NE SEI Pier.  So this is certainly now farther from the south wall than ITMY STS2-B as well as any other previous Roam position.  The attached plots show my typical plots comparing quiet time [18 June 1200 utc] to a windy time [16 June at 1800 utc.]  These times are free of EQ activity.

The first plot is just the corner station wind.  The windy time direction is a very steady 90 degrees or right down the Yarm to the CS.

The big news is seen on the X dof plot where the HAM5 roaming seismo is quieter than the ITMY STS2 during the windy period from about 90mHz down by maybe a factor of 2.  Yes, the useism band is generally higher during the windy period.

Bottom line, keep looking while we have a machine functioning with which to look.
