==== Past week report ====
At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun):
 * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables.
 * We hung the RM and set its pitch.
 * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system.
 * We installed the bottom section of the security structure to protect the RM/BS.
 * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses.
 * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame.
 * We brought in the new BF.
 * We installed the BF-IRM rods and IRM top plate.
 * We reinstalled the IM flags and other items that had been taken off to use the winch system.
 * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.)
 * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT).		 ==== 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.
