locking tonight

Alexa, Evan, Sheila, Koji, Rana

We have been locking the arms tonight, with DRMI on 3F and trying to transition CARM to sqrt(TRX+TRY).  

So far no success, although we found several setings which were wrong.  

We tried moving the CARM offset (using the COMM VCO) to -200 Hz (green), and adding a small amount of gain, 1/10 of our nominal gain.  Rana saw that this adds a lot of high frequency noise to CARM.
