Summery:

Locking this morning wasn't too sucessful, it would drop lock at ENGAGE_ASC every time in what seemed to be the same place. Jim W and I decided to run that state by hand in a Guardian terminal. Doing this showed that changing matrix elements in ASC input yaw, for SRC1 from AS_B_REF36I to AS_A_REF36I was dropping the lock. We got Gabriele involved and he saw that the error signal was no longer good for AS_A. Gabriele and Sheila have changed some things around and it seems to be holding lock now though!
