Unit#2 Cartesian Undamped Plant (Transfer Function) Via Matlab
Ran the Modal to Modal (i.e. Cartesian) plan measurement.  This measurement was run WITHOUT DAMPING, and most of it took place while activity was minimal (i.e. quiet).

Results Comments (comparing to the Unit#1 Document)
[pdf plots attached]
Horizontal GS13s:
The magnitude of the plant looks fairly identical to the Unit#1.  The oddity here is the phase of Y ::: What's up with it being 180deg out of phase??

Horizontal CPSs:
Looks fairly similar to Unit#1.

Vertical GS13's:
Similar to the horizontal, the magnitude of the plant, but here we have the RY off in phase by 180deg.

Vertical CPS's:
Looks fairly similar to Unit#1.
