LHO LVEA Tilt Studies at Roam7--With wind from S

Moved the roaming STS2 to position 7 and here report response during wind of 3 July.  Not as windy as usual studies, only about 15 mph rather than 20.  The wind was at 45degrees, that is directly from true South, or, from +Y-X.

Similar to Roam6, the response at Roam7 indicates this position is quieter than the ITMY location, especially in the X dof.  Since this position move was parallel to the 'south' wall wrt Roam6, it makes some sense that the X dof response is nearly identical to the response to wind at positions 6 and 7.  Maybe time to jog north (away from south wall.)  Also, moving away from the 'pinning' potential of BSC4 does nothing to suggests a real pinning effect.
