Unfortunately, the course alignment of the ITMy (BSC1 cartridge test stand) was not done last week.  Today, we started the fine alignment and discovered the main chain was mechanically grounding on one of the F3 magnet replacement blocks.  This required that we adjust the entire table cloth to alleviate this, (and then all 12 BOSEMs to follow that - ugh)!  The chain then swung further forward causing a larger yaw error.  So, we're back to yaw and pitch alignment.  Fortunately, Doug just had a crash course on yaw alignment techniques and is slowly working at it (an iterative process).
