==== Report for week of 3/5 ====
 * We removed the non-vacuum-compatible ballast mass from the BS tank.
 * We secured all the PR2 feedthrough connections with screws.
 * We grabbed an extra empty rack for SRM and set it up next to the one for SR3 (we will stuff them next week).
 * We calibrated the SR2 SF LVDT and FR.
 * We put the SF cap on and lifted and weighed the SF/... section.
 * We moved the filter building bench and tools into the SRM area and started the rebuild of the two remaining BFs (the one from the BS Test Hang and the one with the tilted keystone).
 * Mark finished -v2 of the schedule ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=7779| L1807779]]).
 * Mark worked on slides for the ASJ and LVC meetings.
 * Sawada-san postponed the SRM mushroom work to next week and offloaded it to Mirapro.		 ==== Report for week of 3/26 ====

  * Fujii-san finished tuning.
  * Enzo wired the LVDT, Picomotor and StepperMotor.
  * We measured the keystone tilt at 4 different points and it was at 65.5, 65.5, 65.5 and 65.5.
    So with the differences of 0.1 mm we think we can tolarate this differences.
  * We added cable clamps to the base.
