TCS CO2 alignment laser positions on the CPs in air

Attached are pictures of where the CO2 alignment lasers are hitting near the CPs. Neither look well centered, but it's tough to say since the cloth is held a bit away from the CP and is coming in at an angle. We also don't know where these alignment lasers were hitting before the vent. The TCSX alignment laser was going nicely through the iris, but for TCSY I had bumped one iris during the water line swap (alog90234) bumping it down. 

Both alignment lasers look to be hitting the optic, so I think at this point we will just plan to use the HWS to make any moves with the CO2 once we are closed up and pumped down. 

In the two attached pictures, the bright spot is the oplev, the alignment laser is the faint cross pattern.
