ITMY CO2 laser central heating still a bit misaligned
On Friday we locked the interferometer at 50W and then turned on central heating on CO2Y for OMC scans. I finally got around to looking at the HWS data from these times. On the Hartmann it looks like the interferometer beam (first plot) is up and left compared to the central heating CO2 beam (second plot).
From Camilla's pico'ing logs it looks like we might want to go more +x and +y on the periscope picos.
Quick movie also attached, we turn on the CO2 about halfway through this movie.

Good catch Georgia. It looks like CO2X might need more pico-ing too! See alog 62776
