Post Maintenance Locking:
Tried to use H1 Manager Gaurdian for initial alignment.
It struggled to get green arms just right, but was able to get through initial alignment just fine.
After that it re-requested initial alignment agian, TJ and I then took over and started the normal locking process with out H1 Manager.
Once I started locking it was smooth sailing all the way up to NOMINAL_LOW_NOISE
Comissioning button set so Elena can do some tests.
NUC 30 (DARM screen) needs to have GDS removed from the channels to run correctly for more than an hour or 2.
22:05 IFO taken to NLN_Cal_Meas
22:18 Erik Von Reese turned GDS back on the DARM screen. we are trying to determine how long it takes to freeze the DARM display.
