[Sheila, Jenne]

Sheila remembered that there are some ASC offsets that change in ASC engagement, and pointed out that those could be affecting our ability to lock.  In the attachment we see that the POP18 drops and POP90 comes up a bit when the AS36Q filter banks change their SWSTAT (which is them turning off the offsets).

We put in offsets in the MICH ASC sensor AS36Q when we have DRMI locked before the CARM offset reduction, in preparation for switching from AS45Q to AS36Q.  But, once we're engaging the full IFO ASC, we want to get rid of those offsets.  Sheila had moved the offset turn-off from PREP_ASC_FOR_FULL_IFO to the end of ENGAGE_ASC_FOR_FULL_IFO in September of last year, but maybe we should move it even further down the sequence, to after the arm soft loops have converged. 

However, I'm not sure that this is the thing that is killing the lock, since it happens ~80 seconds before lockloss. 

For now, we've followed the hands-off procedure and since we've had several locklosses in a row, Jim has just completed initial alignment, and we'll see how this acquisition goes.
