MWAHAHAHA! Good Luck!

Run the "Zero LSC Offsets", which can be found on the blue shell script button on the lower right corner of the C1LSC.adl screen. This script only works on op440m.
Run the "Align Full IFO" script from IFO portion of the C1IFO_CONFIGURE.adl screen. This works best on rosalba, but also works on op440m.
Run a $SCRIPTS/DRFPMI/bang/nospring/c1_watch_dr_bang in a terminal. The watch script will output a message telling you it's tickling the IFO, and how long it has been doing this.
Start a $SCRIPTS/LSC/offloadMCF running, if one isn't already. This works better on op440m.
Once a lock is acquired, the "watch" script should run a script that ramps gains and changes some signals. Once it is done, the watch script will output messages saying the IFO is LOCKED, how long it's been locked, and what the arm powers are. Immediately after lock, both arms should be around ~0.5.
While the IFO is LOCKED and the arm powers are at ~0.5, run $SCRIPTS/DRFPMI/bang/nospring/cm_step in a terminal, on the same machine on which c1_watch_dr_bang is running.
Wait for the happy music.
