Stepped CO2 powers down from 1.7W to 0.9W each into IFO
Elenna, Sheila, Kevin, Matt, Camilla
For some thermalization tests, at 17:05UTC we stepped CO2 powers down from 1.7W to 0.9W each into IFO. Expect majority of thermalization to take ~1hour.
Beforehand, Sheila plugged in the freq noise injection cables in the LVEA PSL racks and Elenna turned on the AWG_LINES guardian.
I'm adding a detchar tag here in case anyone is wondering where all the lines are coming from in the data around this time- these are purposefully injected lines. If AWG_LINES is injecting, it will be in state 10. When IDLE (no injections), it is in state 2.
