Indicators
attachment:green.png complete	attachment:orange.png intermediate state	attachment:red.png nothing happened	attachment:black.png gave up

Step 1. X arm alignment for IR
action	description	status	notes
setup DC_PD at an available port	to find a fringe	attachment:green.png	attachment:help.png put Thorlabs PDA255 at AS
align BS, ITMX and ETMX		attachment:green.png
place TRANS_MON_PD		attachment:red.png
hook it up TRANS_MON to ADC	`c1iscex`	attachment:red.png
make a simple mod/demod system	to lock the IR without `c1lsc`	attachment:red.png
feeding back the signal to MCL	to lock the IR	attachment:red.png
A2L for IR	for precise alignment	attachment:red.png

Step 2. Re-alignment of green
action	description	status	notes
change beam axis		attachment:red.png	attachment:help.png
rearrange the optical setup at X end	if necessary	attachment:red.png
lock the green to X arm		attachment:red.png
