BSC8 SUS Work
Because I don't see a current a log, I'm posting what I know for today. On Friday afternoon we completed adding the balance of the SUS payload to the ISI table.  The SEI crew then balanced the table but left it locked so we could make a round of Romer arm measurements on the ITMy.  Still hunting for the ~6mm y-axis error, we made some measurements of the upper structure structure relative to the ITMy HR surface.  We have had some manufacture errors with these upper structures, so we wondered if there were more that we had not found.  At first glance, based on these measurements, the suspension position within the structure does not seem to be the source of our error.  The ISI was unlocked and the suspensions unclamped for the night.  I believe Garcia and Vincent were going to start testing the systems but I'm not sure their status.  
Today, Dennis continued the 6mm hunt by looking at our alignment templates which were used when fixing the ITMy to the table.  These do not appear to be the source either. As of discussions this afternoon Dennis, Doug, and Jason anticipate working tomorrow morning to redo the EDM measurements.
