Scintillators above and below prototype, 49cm apart. Scintillator width is 13cm. Prototype placed on lower scintillator with straws at 90 degrees to long axis of scintillators.
The fits are not great but all err in the same direction. By eye I would have picked the MPVs for the histograms below at 5.5 and 3.5 x10^3 giving a ratio of 1.6 for the 50 sample integration, tracked ~vertical hits.
