The alignment of the CO2 lasers somehow at some point became bad. The image of CO2Y mode on the Hartmann looked like a sausage (probably clipping), and CO2X was clearly misaligned from the ring heater and IFO beams.
We adjusted the picomotors on the CO2X and CO2Y top periscope mirrors. To measure the alignment we turned the CO2 on after each step on the picomotor and looked at the spot position on the HWS. TVo, Danny and Dan took screenshots of the spot position measured on the Hartmann which they will post later.
Initial position (x, y) Position now (x,y)
CO2X -14935, 12200 -14935, 3200
CO2Y -48170, -27274 -50179, -28274
Since pico'ing we've acquired DRMI very quickly (once), and powered up to 20W without a problem.
I also tuned the calibration on the rotation stages for both ITMX and ITMY because Corey and TJ noticed that it wasn't close enough for the TCS power guardian to be happy and the rotation stage was jittering around a lot. This also gets us closer to the requested values for CO2 Power.
