==== 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.
==== 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.
