Jenne, Sheila, Keita, Camilla

At the end of engage_asc_for_full_ifo we have a converge checker for ASC and the ADS 3 loops (ITMs).  We have lost lock several times shortly after moving on to engage the other ADS loops in engage_soft_loops (see plots from Camilla here).  The initial alignment reseting that Jenne Keita and Camilla did (54798) seems to have helped us to come into lock with smaller ADS error signals, so that is an improvement.  In the attached screenshot ADS 3 comes on at -220 seconds when we are in the state_engage_asc_for_full_ifo, as this converges it brings the other ADS error signals closer to zero.  The convergence checker was waiting for ADS3's error signals to be below 6 before moving on to soft loops.  We lost lock a few seconds after engaging the other ADS loops, so for now we have reduced the convergence threshold from 6 to 2. 

This may mean that we sit a while longer in ENGAGE_ASC_FOR_FULL_IFO.
