IAS needed a 0.2 mm shift to the North (+X) to bring the SUS into spec position.  I closed the RZ loop at the past (last few weeks while position loops were NOT closed) location(-16200nrad); then I drove the X degree 200000nm from its free hang position.  Jason was unable to see this change and it turns out that this amount of shift is barely out of the instrument resolution.  I drove it another 100um and the shift now is revealed.  The free hang position of the HEPI X Dof was -8000 so I've rounded the Bias Target to 300000.  I believe this position will satisfy IAS.

The Ry Dof was unstable so that will have to be worked out before HEPI can be unleashed completely.
