SVT weight

  1. Total weight of SVT + SSD + cables = 166 kG (David Lynn)
  2. Geometry y2003a
    === Weight of SVTT : 284.656 +/- 0.194435 [kg]
    === Weight of FTPC : 97.8858 +/- 0.0415942 [kg]
    	
    FTPC = 97.85 kG;
    weight of SVTT - 2*FPTC = 88.88 kG
  3. Geometry y2005x
    === Weight of SVTT : 299.247+/- 2.76217 [kg]
    === Weight of FTPC : 99.2088 +/- 0.818635 [kg]
    	
    weight of SVTT - 2*FPTC = 100.8 kG

There is difference a factor of 1.7 between real (D.Lynn) weight and weight in simulation.
