 * 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 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.
 * ?? Finish recovering IM OSEM alignment.

==== Plan for week of 3/12 ====
 * Shoda-san at Mitaka.
 * Mark at ASJ (Chiba) Fri, then Mitaka.
 * Hirata-san vacation Mon 3/5; Kamioka Tue-Thu; Mitaka Fri
 * Others Kamioka Mon-Thu
 * F2F VIS Meeting and Farewell Party for Fabian at Mitaka on Friday.

 * Lay SR3 in-air cabling.
 * Continue rebuild of BFs.
