Interesting data
- X arm cavity
- Both IR and GR
- Glitch investigation of the ITMX ADC
- Glitch investigation of the MN oplev light source
- Y arm commissioning
- Both IR and GR
- Center area commissioning
- MICH 3f lock
- Check the lock information
- ALS CARM/DARM
- Check the lock information
- IMC (Input Mode Cleaner)
