 * Mark and Fabian at Kamioka (plus Enzo for 2 days):
  * Finished rebalance of IM
  * Reinstalled IRM, adjusted OSEMs
  * Replaced broken Type 3 cable on IM-H1 OSEM.
  * Fixed issues with k1visbs real-time model.
  * Started TFs from IRM OSEMs to IRM and IM OSEMs.
 * Mark, Fabian and Enzo

 * Mark, Fabian, Enzo
  * Cabled IM picos and used IM yaw pico for adjusting RM. (Later, a wire broke at the connector, disabling the IM yaw, but we were able to continue by manually rotting the pic.)
  * Helped Takahashi-san in adjusting BF.
  * Initial round of adjustment made transverse perfect but overshot in longitudinal and made vertical unstable.
  * Second round of adjustment made vertical stable but left longitudinal offset.
  * Concluded that we can probably manage without bringing the BF back to Mitaka, but it will take some careful surveying of the existing offset and several more days of adjustment.
