Tuning of optimal weight for BF GAS

• We tuned weight of the Dummy Payload (DP) to the optimal one for BF GAS

   Optimal weight [kg]          Resonant freq. [Hz]          Height of keystone [mm]
  -------------------------------------------------------------------------------------------------------
       202.78 +/- 0.1                        0.397                                     67.5

(cf. BF optimal weight measurement in Mitaka: JGW-T1605099)

• We loaded flanges, shackles and other stuffs on the DP for temporary use
  • We'll bring some suitable weights from Mitaka for immediate necessity to continue the installation work (maybe in next week)
  • Anyway we have to procure additional masses

Cabling and connector assembling

• We are on the way of making connectors for GAS LVDT, stepper motors and picomotors
• Setup of the driver circuits around the DGS rack is also ongoing in parallel
