 * Type B Past Week Summary
  * Mark and Hirata-san worked at Kamioka, with valuable help from Enzo (on loan from Type Bp team).
   * We got all the adapter cables for the BF made (Hirata-san did some work on Monday at Mitaka).
   * We installed the extension for the BF yaw pico on the IM pico adapter cable.
   * We got all the in-vacuum and in-air cabling for the IM OSEMs done.
   * We tried to install the stepper and LVDT adapter cables but realized we didn't have enough information on which wires was which. (We later tracked this info down but did not have time to do anything with it - we would have needed to do the rest of the in-vacuum and in-air cabling and set up the stepper motor and LVDT drivers, so we concentrated on the OSEMs.)
   * We plugged in the IM OSEMs, set gains and offsets, and did a noise test (analysis and klog pending).
   * We mounted the OSEMs on the IRM and routed the cabling neatly.
   * We released the suspension.
   * We adjusted the OSEM mounting plates to center the OSEMs on the flags.
   * We adjusted the OSEMs in/out to midrange.
   * The suspension is now ready for OSEM-OSEM TFs!
=== Type B (Mark) ===
==== 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.
