Late last week after we aligned the entire SR chain with the PSL beam, re rediscovered that we had left the ITMx clamped.  So this morning, I entered through HAM 4 (since we have blocked off the door to BSC3 for laser safety reasons) and unclamped the ITMx.  Hopefully the realignment now will remove some of the bias we had to put on the BS to shoot to the center of SR3.
