=== Summary of last week ===
 * ETMY misalignment was fixed.
 * Investigation of polarization is going on.
 * We keep central area for a while and keep DRMI characterization specially for control.
 * We confirmed that we would have an engineering run on 7/13.

 * 12pm-6pm
  * PEM needs ~10min after run.
  * CAL needs free swinging Michelson.
 * Michelson
 * 		 * Low finesse cavity can have mode hop in anywise, whether with/without polarization issue.
  * Needs changing Gouy phase by changing PR2(Stefan).
