plans for this evening summary
- Right now Jennie W is tuning line heights for an OMC mode matching measurement while the violin modes damp, we will go to observe after this quick test and when the violins allow.
- Corey has a template set up to evaluate MICH and SRCL feedforward filters once IFO has thermalized (turn ff gains to 0, switch filters to FM9, then ramp gain back to 1)
- Either Corey or Ryan C will run a calibration measurement set once the IFO has thermalized.
- If we loose lock due to the 80kHz PI (mode 29) despite the guardian changes made yesterday, we can try to step the EX ring heater down from 1.3W on both segments to 1.2W on both segments. ezcawrite 1.2 H1:TCS-ETMX_RH_SETUPPERPOWER ezcawrite 1.2 H1:TCS-ETMX_RH_SETLOWERPOWER
