Distance between fpp ch1 and ch2
Measured four corners ( look from the VDC)
Lower left 15.43" Upper Left 15.35"
Lower right 15.40" Upper right 15.44"
This is the distance between the upper edge of ch1 to
the lower edge of ch 2. So one has to add 4.90" to
get the distance between midplanes of the chambers.
