After previous CO2 steppers alog 66465 and alog 66429, we are going to try steps down of 0.2W and 0.1W on CO2X and Y every 20 minutes tonight. Georgia and Craig have turned on 74.7 Hz and 4.5 kHz AWG_lines: alog 66710.

I have scheduled the script to run at 8pm - 1am and 2am - 7am if the IFO is in NLN. Two times to increase chances that we'll get a successful measurement. If we loose lock while the test is running ISC_LOCK will take control of the CO2s and turn them off.
