==== Report for week of 2/26 ====
 * We routed all the cables from the BF level up via the flying saucer to the SF.
 * Hirata-san tried filing the SF cap to improve the fit, but without much success.
 * Hirata-san installed the Cu segments and cable clamps on the SF cap and the SF LVDT and FR cables.
 * We cabled and tested the BF cap picos and the SF LVDT and FR. (The LVDT still needs a full calibration.)
 * We worked on recovering the IM OSEM alignment. 		==== Report for week of 4/9 ====
 * Mark glued prisms and magnet/standoff assemblies on the SR3. The SR3 needed to be raised in the box by 0.7 mm to make the prisms go on at the right height, which was done using M4 washers under the PEEK feet.
 * Mark glued ferromagnetic disks on the last 5 IM flags. This completes 2 sets, for SR3 and SRM.
 * Mark configured two pico motor drivers ordered by Takahashi-san as SR3-IM and SRM-BF.
 * Enzo and Kozu-kun finished preparing and calibrating the SF and BF for SR3 and almost entirely finished with those for SRM.
 * Hirata-san worked on building two IMs for SR3 and SRM. The SR3 one just needs to have flags attached and to be weighed; the SRM needs another few hours work.
 * Shoda-san worked on the design of the metal SRM, on the LBB ballast mass, and on the plans for testing the BS in bKAGRA Phase 1.
