I modified the LSC_LOCK guardian for observing run as follows.

LOCK_PREP:

I enabled the function to read OBSERVATION snap.
I also enabled to wait for lock acquisition until the earthquake passes.
To avoid misalignment due to the DC position change along optical axis, I disabled clear history of K1:VIS-ETMX_IP_ISC2LVDT_L filter bank.

RESET_ASC_FEEDBACK:

To avoid numerical rounding of SDFs, I changed the guardian so that OpLev/OUTPUT setpoints are rounded at the eighth decimal.

INCREASING_LAS_POWER:

To avoid numerical rounding of SDFs, I changed the guardian so that K1:LSC-REFL_SERVO_SLOW_GAIN is rounded at the eighth decimal.

LOCKING_OMC_FOR_PRFPMI:

Since OMC beacon doesn't seem to work well (klog33999), I disengaged OMC ASC.

LOCKING_OMC_FOR_IAL_WITH_RF:

To implement this state to lock acquisition, I modified this state so that the guardian automatically request ADS to OMC_ASC guardian.

ALIGNING_OMC:

To wait until OMC alignment becoms good, I added the new state to LSC_LOCK guardian named ALIGNING_OMC.
The guardian stays this state until the alignment to OMC becomes good.

RECORD_GOOD_VALUES_OMC:

Since the implementation of this state was not good (LSC_LOCK guardian stops for more than 10 seconds), I modified it.
Now, record is done without stopping the guardian process.

Guardian edges:

To implement the OMC initial alignment to lock acquisition, I modified the guardian edges as shown in fig1.
Note that, LOW_NOISING_SUS_FOR_PRFPMI state is directly connected to LOCKING_OMC_FOR_PRFPMI before the modification.
