Aligned the CO2Y beam to the IFO beam using the HWS image from this morning lockloss.
Today using top periscope mirror (TCS Y CO2 pico #3) to align beam onto ITMY. Starting pico values were (-6250, -2500). Changed pico to (x: -12250, y: -3500). CO2Y 2W applied for ~90 seconds then left at 0W too cool down for 5 minutes. Attached images of before and after with annulus and central masks and intermediate steps (labeled in filename). Also IFO and CO2 beams overlayed in attached pdf. Finished at 11:24am.
History/links: Periscope previously roughly aligned in alog62701, on-table alignment accidently changed in alog62961, we went on table in alog63568 to improve on table alignment using FLIR.
