  2. ETM drive diagonalization
  3. Commission the red cavity lokcing signals.
  4. Lock the arm cavity on red.
  5. Make a mode scan of the red resonances
  6. Commission the common mode hand-off including the AO path.
  7. Measure difference between red and green locking offsets.
  8. Commission the length feedback path to the ETM top suspension point to suppress microseism.
  9. Asses the status of the reference cavity temperature controls.

Red team:
