keyword=Right Arm Gas Cerenkov position
The Gas Cerenkov is not exactly centered on the bottom rail. Not that
centering it on the rail centers it on the VDCs, it is just where we
usually position it. The tape says 16 1/4" on the left side and 16 3/4"
on the right side. So, it is 1/4" to the left of the center of the rail
it sits on. Nobody has said anything about the positioning, so I put
C-clamps on the rail to keep it from shifting position from where it is.
