QUICK SUMMARY:

IFO is LOCKING at ENGAGE_ASC_FOR_FULL_IFO

Some ALS Locking issues as we were locking, thought to be due to recent table work that required new TRX gain normalization, which conflicted with ALS Gurardian Scan Alignment. The gain of 3.0 (up from 1.5) has been temporarily accepted in the SAFE.snap temporarily until more tuning is done tomorrow (attached SDF).
