==== 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.

 * '''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.
 * We received the SR3 but found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK).
 * We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday.
 * Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws.
 * Fujii-kun, Enzo and team finished the preparation, adjustment and calibration of the SFs and BFs.
 * Fujii-kun and Yamamoto-kun got the SR3 real time model running.
 * Enzo finished setting up the SR3 and SRM racks. (The SRM rack still lacks a front-end, and power and network connections, but the SR3 is now ready for testing.)
 * Shoda-san worked on getting quotes for the ballast masses, on design of the SRM metal mass, and on splitting the BS model to reduce the load on the front-end computer.
