As discussed last week during the SEI call, we are going to try to subtract the unwanted coupling from Z drive to RZ T240 Signal.

While we are still investigating the cause of this coupling (magnetic coupling test in the Staging building, Stage deformation FEA at MIT...), online subtraction is for now our only option to move forward.

This test can't be performed at the univeristies (Stanford and MIT protoypes use STS2's and the Stage 1 structures are different) so we have to try it at the sites.

Work permit #4626 has been filled and approved.

I am going to start modifying the Two stage Master simulink. We'll coordinate with install and commissioning activities as for when and which unit to use to test this modification.

Depending on results, we'll decide whether to revert or propogate this feature.
