 * IX: To the finalization.
 * EX: Alignment for the green beam was finished. To the finalization
 * IY: Height adjustment is on going.
 * EY: Mirror cleaning is on going in Mitaka. Measurement system had a problem. The shipping will be in the end of next week at earliest.		  * IX: Still some cabling from payload have problems. To the finalization.
 * EX: Aligned for the green beam again. To the finalization
 * IY: F1 was recovered. Adjustable range of F0 was extended ([[https://www.dropbox.com/s/a8p7m6luxz6ndwn/Height%20range%20rev.pdf?dl=0|Height range]]). Range of BF damper should be taken into account. The height adjustment was scheduled in the week of 7/26.
 * EY: Mirror cleaning was almost finished. The shipping will be in the next week (transported after holidays).

 * Separation of rack in 2F: This is scheduled on 7/16.
 * New vacuum pumps for V-chambers: Considering the port location.
 * Extension of cables for picomotor drivers: Tested in EYV.		  * Separation of rack in 2F: It was finished on 7/16.

Adjustable height range of the filter chain in IY
 * [[https://www.dropbox.com/s/i7e0grqv324sdfz/Height%20range.pdf?dl=0|Present height range]]
 * The condition of F1 stepper motor is the same as the F3 in IX. We tried to move the motor with the stand alone driver, but the FR is still not working.
  * The motor is still not working?
  * The FR slider is stuck?
 * The range of BF is too small. Check the mechanical stopper.
 * Tune the F0 more to lower frequency (now 0.4Hz) in order to extend the range.		 ----------
