==== Past week report ====
At Kamioka (Mark, Fabian, Enzo, Hirata-san):
 * We improvised a solution for ballast mass on the BF, using some heavy dog clamps meant for pedestals, washed and wrapped in foil. We we use them for the duration of the BS Test Hang and then swap them out for custom masses.
 * We rearranged the BS rack, closing the gaps between boxes (per request of Miyakawa-san. We also renumbered some boxes, connectors and cables so as to use zero-based numbering (#0, #1, #2,...) throughout.
 * We routed the OSEM cables into the external cable rack (rather than through the PR2 area).
 * We connected up the BF LVDT, and BF fishing rod stepper motor.
 * We installed a signal generator for the LVDT.
 * We connected the super motor driver box to the Internet and attempted to set it up, but with no success so far.
 * We found the final picomotor driver (we have been using the one from TAMA in the clean booth).
 * We found many items that we will need soon, including the copper ring for the SF.
 * We found issues with the digital system (the computer driving the rack had been changed from k1pr2 to k1bs, which causes problems) and worked with DGS to fix them. It now mostly works but the real-time model crashes from time to time.
 
==== Plan for coming weeks ====
 * Everyone (Mark, Fabian, Enzo, Hirata-san) next week at Kamioka		 ==== Report for week of 2/19 ====
 * We did TFs from the IM OSEMs.
 * We secured the cables inside the BF, added the cap and anchored the cables from below the BF to the cap.
 * We lifted the BF/... section with the load gauge adapter and measured the weight, which was about as expected.
 * Based on the measured weight, Fabian prepared an 800 g set of masses for the top of the BF.
 * We added the AF crossbars and the section of the SS below the SF and craned in the SF.
 * We installed the SF-BF rod and flying saucer and suspended the BF/... section. With the 800 g placed temporarily on the BF, the SF keystone floated at about mid-range.

==== Plan for week of 2/26 ====
 * Shoda-san at Mitaka.
 * -
 * Enzo at Mitaka Mon 2/26.
 * '''Remove LBB temporary ballast masses from BS chamber.'''
 * Route cables up to under SF.
 * Check/adjust total mass and balance of BF/... section, especially IM OSEMs.
 * Cable and calibrate SF LVDT.
 * Add Cu segments to SF cap.
 * Install cap.
 * Lift SF/... section and check total mass and balance.

==== Plan for week of 3/5 ====
 * Shoda-san at Mitaka.
 * Hirata-san vacation Mon 3/5, then Kamioka
 * Others at Kamioka.
 * -
 * Get SRM tank mushroom section installed (Hirata-san, Kimura-san)
 * SR3 rack setup.
 * Other tasks TBD.

==== Plan for week of 3/12 ====
 * Shoda-san at Mitaka.
 * Mark at ASJ (Chiba) Fri 3/16.
 * Hirata-san vacation Mon 3/5, then Kamioka

==== Plan for week of 3/19 ====
 * Mark at LVC meeting
 * Shoda-san, Fabian at Mitaka

==== Plan for week of 3/26 ====
