==== 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 4/9 ====
 * We packed away the SRM SF and BF.
 * After several failed attempts with one secondary prism, Mark finished the SR3 prism/magnet gluing.
 * Tanioka-kun built two IRMs (less OSEMs).
 * Enzo built an RM.
 * Kozu-kun and Enzo calibrated one set of 6 IM OSEMs for SR3. (6 OSEMs for SRM remain to be done.)
 * Hirata-san aligned the assembly frame, installed the interface bars and IM ring, and installed the IM.
 * Eleonora and Izumi-san revisited the BS length to tilt coupling, which had degraded, and got it working again.
